Vladimir [108]

The function of the cell cycle is the growth, repair and reproduction of cells.

The process through which a cell goes through its phases of growth and division is referred to as the cell cycle. During the majority of its existence, a cell is said to be in a state known as interphase. It is during this phase that the cell develops, copies its chromosomes, and gets ready to divide. Following this, the cell exits interphase, starts the process of mitosis, and finishes its division. The new cells that are produced are referred to as daughter cells, and each of them will experience its own unique interphase before beginning a new cycle of the cell cycle. The cell cycle helps the cells to undergo growth and division. In case of any damage, the cell cycle contributes to the repair mechanism of the cells.

What is the Cas9 enxyme used for?
frez [133]

Answer:

RNA

Explanation:

CRISPR system was discovered by a Japanese scientist. Naturally bacteria and many other prokaryotes have CRISPR system in their genome which they use as a self defense against a pathogen which is invading them. It consists of inter spaced, short palindromic nucleotide repeats which encode a guide RNA (gRNA). This guide RNA (gRNA) recognizes the target sequence on the pathogen. The gRNA is followed by Cas9 enzyme which along with the gRNA plays a very important role in breaking genome of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by non homologous end joining.

But nowadays, scientists are using this system for genome editing and incorporating desired gene between the two ends which are cut down by CRISPR Cas9 system.
