There is strong evidence that gene editing is already here and is almost ready to start being used in humans. As mentioned in previous posts, CRISPR/Cas9 has already being used on embryos. However, there are some drawbacks that definitely scare people away. This is where David Liu comes into play. He was a professor at…

Human embryos have been edited by using CRISPR/ Cas9 technology. This is the first time that this genome editing technology have been used in humans, and definitely is the beginning of a new era in medicine. CRISPR  is a high efficient genome editing tool, that can target almost anywhere within the genome. However, there had…

What is CRISPR-Cas9?

CRISPR is the bacterial immune system in which the bacteria is able to integrate the viral DNA in its genome, and then use it against that specific virus when the bacteria is attacked.  This specific immune system is conformed of the  guide RNA (gRNA), integrated from the virus, and a protein called Cas9. The gRNA…
