what is crispr
CRISPR is a molecule that finds a string of DNA code, locks on and makes a precision cut. And because scientists can tune it to target any genetic sequence, they can use it to turn genes off or replace them with new versions.
What is CRISPR-Cas9?Scientists in Japan were the first to discover CRISPR in the DNA of bacteria in 1987. In their attempts to study a particular protein-encoding gene in E.Coli, the researchers noticed a pattern of short, repeating, palindromic DNA sequences separated by short, non-repeating, âspacerâ DNA sequences.f scientists are able to nail down the use of CRISPR/Cas9 in human germ cells, thereâs no question that it could confer major benefits. Namely, the technology could eradicate hereditary diseases such as cystic fibrosis, sickle-cell anemia, and Huntingtonâs disease from a family line altogether.
