Answer:

D.It’s an example of polygenic inheritance.

Explanation:

Polygenic inheritance occurs when more than one gene regulate single genetic trait. Human skin color is regulated by more than one gene and follows quantitative inheritance wherein total number of dominant alleles of all genes determine the skin color. Formation of various gene combinations by multiple genes regulating the skin color results in world wide variation of the trait as well as variations of skin color between parent and progeny.

Chloramphenicol binds in the active site of the large ribosomal subunit and inhibits peptidyl transferase activity in the 23s rr
valentina_108 [34]
This inhibition is restricted to bacterial translation because; the peptidyl transferase is an enzyme aminoacyltransferase as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the process of translation. Therefore, inhibition of this enzyme means that the process oof translation wont take place, hence proteins will not be formed and thus the bacteria will die.
