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.

<h3>Oxidative Phosphorylation</h3>

Explanation:

The process by which ATP is generated by utilizing the large amount of energy released during the transfer of electrons from NADH or FADH₂ to the O₂  through a series of electron carrier present in the mitochondrial membrane is called oxidative phosphorylation.

The process of electron transfer is accompanied by the pumping of protons across inner membrane of mitochondria, from the  mitochondrial matrix to intermembrane space establishing electrochemical proton gradient.

The ATP synthase complex present in the mitochondrial membrane allows the protons to move down the proton gradient  as a result enough energy is released to add a phosphate group to ADP and form ATP inside the mitochondrial matrix.
