CAN SOMEBODY EXPLAIN WHAT CRISPR CAS9 DOES PLEASE I AM SO CONFUSED

Molecular Machinations: The Future of CRISPR-Cas9

CRISPR-Cas9 has made genetic engineering easier, faster, and cheaper than ever before. A scientist interested in manipulating a particular gene only needs to search the gene’s sequence for a suitable PAM. Once a PAM is found, the corresponding Cas9 can be ordered or harvested from its bacterial strain (and as I mentioned last week, even if a PAM isn’t found, it is possible to engineer a Cas9 to recognize a new PAM sequence). An appropriate sgRNA (the crRNA:tracrRNA fusion molecule) can be designed by identifying the target sequence 20 nucleotides upstream of the chosen PAM. These sgRNA’s can be engineered by the scientist directly or ordered via synthetic production.

This week's blog is about some of the exciting scientific feats being done with CRISPR-Cas9, and what it may be able to do in the near future. I even slipped in some Covid-19 applications. Check it out and subscribe to the site for weekly science emails!

Molecular Manipulation: CRISPR and Genetic Engineering

If you’ve ever seen the movie Gattaca, then you probably know something about the concept of genetic engineering. However fictionalized that movie may have seemed (my favorite part was a full genome sequence printed on one small tube of rolled up paper), it did bring up a lot of interesting ethical questions that are suddenly becoming more and more relevant.

This week's blog is more information about CRISPR-Cas9 and, more specifically, how it is used for genetic engineering. Check it out and subscribe on the site for weekly science emails.

Molecular Memory: Bacterial Immunity and CRISPR

One of the most efficient ways that bacteria build immunity is through the CRISPR Cas9 system (CRISPR stands for clustered regularly interspaced...

I decided to take a break from talking about Covid-19, so this week's blog post is about bacterial immunity and CRISPR. Check back next week for more information about how CRISPR-Cas9 is used for genetic engineering.
