Genome editing is the control of
adding, deleting, activating, or suppressing specific genes on DNA
sequences. Researchers have recently developed
a new technique for genome editing. The
technique involves a system known as CRISPR-Cas (or clustered regularly
interspaced short palindromic repeats-Cas).
CRISPR is a system used by bacteria to defend against viruses and other
invaders; it targets and cuts DNA in a sequence-dependent manner to turn off or
on genes that could harm the bacteria.
Researchers
are now utilizing this system to better understand and develop new ways to
manipulate genes. In addition to
understanding and manipulating genes, the CRISPR-Cas system allows for
increased accuracy and precision when targeting DNA. This research has the potential to change the
world. Crops could be specifically
altered to reduce or even grant immunity to diseases. This could eventually be developed to work on
people: genetically tailored drugs for your specific genome or changing you
genome to grant immunity/resistance to disease.
One scientist, George M. Church, even predicted the possibility of
de-extinction, human enhancement (develop human bodies suited for space and
other hostile environments). Of course as exciting as gaining control over the
human genome is, it raises the questions is it safe, effective, and morally
right? We are going to have to answer
these question soon.
I have
always found control over the human genome to be fascinating. The potential it has to improve the world is
astronomical, which is why I thoroughly enjoyed reading this article. It showed we are constantly advancing our
techniques and approaches to handling the control of genes on DNA
sequences. When we finally gain the
control over genes, we will be able to help the world and expand in all fields.
