Answer:
CRISPR can also be used to make precise changes such as replacing faulty genes – true genome editing – but this is far more difficult. Customised Cas proteins have been created that do not cut DNA or alter it in any way, but merely turn genes on or off: CRISPRa and CRISPRi respectively.
Answer:
C
Explanation:
Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end. It is that carboxyl group that makes it an acid (carboxylic acid).
I think it’s living but I don’t have enough context to fully tell :( hope this helps
Answer:
b. Cellular clock is the correct answer.
Explanation:
Cellular clock theory states that cells can divide a maximum of about 75 to 80 times, and that as we age our cells become less capable of dividing.
Cellular clock theory directs on the lifespan of organisms. As the many individual cells do not remain to reproduce continually, so this theory implies that aging of the cells is a result of their reproductive limitation and because of cellular aging.
Cellular clock theory is the theory Leonard Hayflick's that describes the cellular aging mechanism and it suggests that as the cell becomes aged it becomes less effective of dividing.
