Cas9 (CRISPR associated protein 9, formerly called Cas5, Csn1, or Csx12) is a 160 kilodalton protein which plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids, and is heavily utilized in genetic engineering applications.
A rumour claimed that the shorts were found zipped and neatly folded; pictures of the shorts, published in 2021, disproved this information. [22] Two months later, closer to where the backpack was discovered, a pelvis and a boot with a foot inside were found. Soon, at least 33 widely scattered bones were discovered along the same river bank.
CRISPR gene editing is a revolutionary technology that allows for precise, targeted modifications to the DNA of living organisms. Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system, that allows "cutting" of DNA at specific locations and either delete, modify, or insert genetic material.
Cas9 uses cell-specific promoters allowing a controlled use of the Cas9. Cas9 is an accurate method of treating diseases due to the targeting of the Cas9 enzyme only affecting certain cell types. The cells undergoing the Cas9 therapy can also be removed and reintroduced to provide amplified effects of the therapy. [133]
INTERVIEW: The rebellious, joyful sprite of ‘Girls Just Want to Have Fun’ is about to embark on a farewell arena tour in the UK. She talks to Adam White about Trump, masturbation anthems, and ...
Jennifer Doudna was born February 19, 1964, in Washington, D.C., as the daughter of Dorothy Jane (Williams) and Martin Kirk Doudna. [2] [17] Her father received his PhD in English literature from the University of Michigan, and her mother held a master's degree in education.
A new CRISPR gene editing/repair tool alternative to fully active Cas9 is reported – Cas9-derived nickases mediated homologous chromosome-templated repair, applicable to organisms whose matching chromosome has the desired gene/s, which is demonstrated to be more effective than Cas9 and cause fewer off-target edits.

In December 2008, a man from Sydney was convicted of possessing child pornography after sexually explicit pictures of underage characters from The Simpsons were found on his computer. The New South Wales Supreme Court upheld a Local Court decision that the animated Simpsons characters "depicted," and thus "could be considered," real people. [ 13 ]
