C. 42
Explanation:
A sperm cell is a sex cell which is a haploid cell and thus has half the chromosomes of a somatic cell which is a diploid cell.
The ribosomal RNA studies that led to the division of prokaryotic organisms into the bacteria and the archaea were begun by Woese.
Ribosomal RNA makes the maximum portion of RNA in the cells. However, it is not translated into proteins. But it plays a major role in the translation of m-RNA. They are responsible for deducing the order of the amino acid sequence and linking the amino acids together to form the polypeptide.
Archaea are a group of organisms that are similar to bacteria, yet have evolutionary differences. They are found in extreme locations like hot spring, salty water bodies, or areas where methane if formed. Therefore, they are also known as extremophiles.
