Many of the powerful technologies we’re developing today hold the potential to fundamentally reshape how the world thinks about and goes about global conservation, advancing human health and solving the most pressing challenges in life sciences. Some will impact the efficiency and availability of everyday medicine. While others may contribute to the eradications of disease and the acceleration of possibility through genetics.
What exactly is genetic engineering? Why is it so important? And how are we applying it? Read below to better your understanding of this complex field of study.
Genetic engineering is best defined as the act of modifying an organism’s DNA sequence with the use of biotechnology. Genetic engineering can be used for editing a single base pair of DNA, multiple base pairs of DNA (a sequence), to editing entire genomes by either up-regulating, down-regulating, knocking-in or knocking-out genes (e.g. insertion, deletion or replacement of specific genetic material).
There are numerous techniques for genetic engineering, with the most common and widely used technique being CRISPR.
At Colossal, we currently focus on the application and advancement of CRISPR for the purposes of de-extinction and climate change reversal.
Genetic engineering is used to help humanity advance treatments for genetic disorders, gene therapies, DNA fingerprinting, vaccines and pharmaceutical products. Further applications include sustainable plant and animal food production, diagnosing diseases and conditions, medical treatment improvement, as well as production of vaccines and other useful drugs.
Genetic engineering applications of animals include advancing human health, enhancing food production, reducing environmental impact, optimizing animal health and welfare and production of cutting edge industrial applications. Other world-bettering uses include eradicating malaria, organ donorship, and of course, the slowing of and reversal of the extinction of species.
“Working toward a Colossal achievement like bringing back an extinct species is the kind of thing that our brightest minds want to do.
Colossal's ambition is an inspiring example of what can be done, and the technological by-products of doing it will invigorate the industry of generic engineering. I am excited to see this happen as fast as possible, because a new generation of bright minds, using this new technology, can do something about the ecological crisis they are inheriting. Our unbridled exploitation of nature has fought a war with evolution, and the natural world doesn’t have a chance without us. Precision genetic engineering can begin to reverse this damage, by creating bacteria that eat plastic, corals that are resilient to heat, and restoring ecological balance in threatened habitats.”

[ CELLS / NUCLEUS / CHROMOSOMES / GENES / DNA / RNA / CAS9 ]
Cells are the basic building blocks of all living organisms. The human body is composed of trillions of cells. A cell provides structure for the body. A cell can take in nutrients from food and convert the nutrients into energy. Cells perform many functions, and thus contain specialized parts for each function, called organelles. The organelle that contains hereditary information is called the nucleus.
The nucleus is located inside the cell. The nucleus is where all genetic material, i.e. DNA, is stored in the form of chromosomes. In addition to storing all of the genetic information of the cell, the nucleus acts as the cell’s command center, sending directions to the cell signaling that it's time to grow, mature, divide, or die.
Inside the nucleus, DNA molecules are packed into thread-like structures called chromosomes. The human genome contains over 3 billion base pairs of DNA, in order for the nucleus to be able to hold all of this genetic material, it has to be stored as tightly wound DNA structures. The amount of chromosomes inside a nucleus varies from species to species. Human beings have 46 chromosomes, while elephants have 56 chromosomes. The amount of genes on each chromosome varies from chromosome to chromosome.
A basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein, found in all living things; some genes form a set of instructions for the manufacture of proteins. Colossal has already sequenced the genes of both the Asian Elephant and the Woolly Mammoth.
Deoxyribonucliec acid, the molecule inside cells that contains genetic information responsible for the development and function of an organism; DNA is made up of a double-stranded helix held together by a sugar-phosphate backbone and weak hydrogen bonds between purine-pyrimidine nucleotide base pairs: adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C)
Ribonucleic acid, a nucleic acid that acts as a messenger carrying instructions from DNA for controlling the synthesis of proteins; however, in certain viruses, RNA rather than DNA contains the genetic information
Cas9 (CRISPR associated protein 9) is a 160 kilodalton protein which plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids, and is heavily utilized in genetic engineering applications; its main function is to cut DNA and thereby place new DNA to alter a cell's genome
The field of genetics truly began when James Watson (USA) and Francis Crick (UK) published a scientific paper called "Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid" in the scientific journal Nature. This world-changing piece was the first to define and describe the double helix shape of DNA. Ultimately, this started a wave of interest in genetics by the scientific community, and in the years since, as technology has advanced, the field of genetics has advanced along with it. For example, the more powerful microscopes grew, the more scientists could visualize and manipulate. Ultimately, leading to where we are today, with a process as complex and precise as CRISPR Cas9 genome editing.

CRISPR is an engineered cellular technology used for recognizing and cutting a specific code of DNA inside the nucleus. Once this DNA is cut, a laboratory modified version of DNA is inserted and reanneals the cut DNA by binding to the specific code.
CRISPR technology is originally an innovation of nature and was first observed in bacteria, specifically in its non-membraned, simple cells. But, scientists have been able to re-engineer this CRISPR technology to work in eukaryotic cells - meaning cells with a nucleus and organelles, all enclosed in a plasma membrane. These are the types of cells humans and animals have.
In mammalian cells, such as an elephant or a Woolly Mammoth, CRISPR works with an enzyme called Cas9 to modify genes. A CRISPR-Cas9 complex will use a single guide RNA from CRISPR to guide and recognize a specific sequence of DNA, where the Cas9 molecule will cleave those strands that are complementary to the CRISPR sequence. This allows for the reinsertion of the laboratory engineered DNA, as mentioned on the image below. Ultimately, giving us the ability to insert cold-resistant characteristics into elephant DNA - leading to the de-extinction of the Woolly Mammoth.

Our Process :
Now with Colossal, Church is directing the world’s first feasible approach to species restoration, specifically of the Woolly Mammoth.
Below is a step-by-step breakout of the progress.
George Church and a member of his lab, Eriona Hysolli, visit Chersky-Siberia, Russia in 2018, looking for Mammoth bones and observe what would have been the Mammoth Steppe.
At the Mammoth Museum in Yakutsk, George Church and Eriona Hysolli acquire some significant tissue samples. These tissue samples allow their work to continue identifying the genetic differences between Mammoths and modern Asian elephants.
With Mammoth and Asian elephant tissue samples, Church and team compare the two genomes and insert key factors of the Woolly Mammoth genome into the Asian elephant genome.
Church and his team sequence the Woolly Mammoth genome from samples collected during their excursion to Chersky-Siberia.
Church’s team select 50+ traits that will enhance the cold-resistant ability of an Asian elephant.
Cold-resistant traits including shaggy coats, smaller ears, cold-adapted forms of hemoglobin, excess adipose tissue production, etc.
These traits belong to the Woolly Mammoth genome and are inserted into the Asian elephant’s genome.
CRISPR libraries are made up of synthetic Woolly Mammoth DNA.
CRISPR technology allows Church and our science teams to cut the Asian elephant DNA and paste the Woolly Mammoth DNA in its place. Before the Woolly Mammoth DNA is inserted into the Asian elephant genome, a CRISPR library is developed which holds the Woolly Mammoth DNA that encodes the 50+ identified traits.
Headed by George Church, our science teams use CRISPR to insert the 50+ modified cold resistant genes into the genome of an Asian elephant.
The CRISPR libraries enter the elephant genome via a delivery system. Once in the genome, a CRISPR/Cas9 complex containing our programmed single guide RNA binds to the identified gene in the Asian elephant genome. This complex then cuts the double strands of the Asian elephant DNA and allows for the insertion of our programmed hybrid DNA in its place. This cut and paste process repeats individually for each gene.
Each new cell replication will express our edited gene of interest, the hybrid gene, and pass that on to future generations. A hybrid gene is an Asian elephant gene that has been edited with Woolly Mammoth DNA to enhance the cold-resistant traits.
The newly made hybrid cells are tested and verified. The cold resistant traits are assessed via various assays.
An assay is an investigative procedure in biology for qualitative assessing or quantitative measuring the presence, amount, or functional activity of a target gene or trait.
A hybrid cell is an Asian elephant cell that has been edited with Woolly Mammoth DNA to enhance the cold resistant traits.
This stage involves a scientific process called Somatic Cell Nuclear Transfer (SCNT).
Somatic cells are any cells in the body that are not egg or sperm cells. Since somatic cells cannot give rise to new life, they donate their nucleus (genetic material) in this process. Our scientists transplant the CRISPR edited somatic cell nucleus into an egg cell, after removing the egg cell’s nucleus. After the egg containing the edited nucleus is fertilized, the resulting embryo carries the edited traits. Once our scientists are confident that the hybrid cells are functioning properly, they begin the embryo transfer process. The nucleus of the donated Asian elephant egg is removed. Our hybrid nucleus, the Asian elephant nucleus that has been edited with Woolly Mammoth DNA, is inserted into the egg as a replacement. Electrical pulses are applied to the egg to simulate fertilization. The egg then begins to divide and grow, becoming an embryo. This is the same process that created Dolly the Sheep.
Once the embryo forms, it is ready for implantation into a surrogate African elephant.
Here, researchers perform SCNT (Somatic Cell nuclear transfer). In an analogous step, and engineered hybrid nucleus will be transferred from a somatic elephant cell to an elephant egg cell and then to a surrogate (or in vitro) uterus.
Gestation in the elephant’s womb
occurs for around 18-22 months.
