From the smallest single-celled organism
to the largest creatures on earth,
every living thing is defined by its genes.
The DNA contained in our genes acts like an instruction manual for our cells.
Four building blocks called bases are strung together in precise sequences,
which tell the cell how to behave
and form the basis for our every trait.
But with recent advancements in gene editing tools,
scientists can change an organism’s fundamental features in record time.
They can engineer drought-resistant crops
and create apples that don’t brown.
They might even prevent the spread of infectious outbreaks
and develop cures for genetic diseases.
CRISPR is the fastest, easiest, and cheapest of the gene editing tools
responsible for this new wave of science.
But where did this medical marvel come from?
How does it work?
And what can it do?
Surprisingly, CRISPR is actually a natural process
