Recommendation

Gene editing has been around for decades, but CRISPR technology has scientists dreaming up new experiments. This gene editing system can specifically modify the genome of various species including our own. While some have raised ethical concerns, researchers are only slowly beginning to understand the strengths and weaknesses of the CRISPR system. In the future, doctors could treat diseases with this new technology and usher in a new field of medicine. Anyone who is interested in the latest trends in genetics and medicine will find this video informative.

In this summary, you will learn

  • What CRISPR technology is,
  • How scientists currently use CRISPR technology in the lab and
  • How future medicines could use CRISPR technology to treat genetic diseases in humans.

Summary

CRISPR technology allows scientists to target and edit specific regions in the DNA.

Researchers have managed to successfully edit genes in the past but CRISPR technology has provided them with an affordable and more precise tool. They first identified the CRISPR system in bacteria as a protein known as Cas9. Scientists can use Cas9 together with a designed guide RNA to precisely target regions of the genome and modify them. Variants of the CRISPR system exist in different bacterial species, which enables researchers to use it in various ways. For example, some CRISPR systems are better suited to target different regions of the genome while another CRISPR system targets RNA instead of DNA, allowing scientists to regulate protein expression at different levels.
