bonufazy [111]

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.

iragen [17]

Suppose bad weather and pollution dramatically reduce the supply of crawfish in Louisiana next year. This would most likely lead to an increase in the marginal utility of crawfish consumption.

Marginal utility of a commodity or service is the change in total utility resulting from consuming an extra unit of that commodity or service.

The marginal utility of a good or service tells about the happiness experienced or the contentment obtained by the consumers as a consequence of the increment or decrement in consumption by one unit.

There exist three kinds of marginal utility. They include positive, negative as well as zero marginal utility.
