Answer:
The correct answer will be option-B.
Explanation:
Sertoli cells are the large somatic cells present in the testis which helps in the formation of spermatozoa. The Sertoli cells create a suitable environment for the production and maturation of the sperms as they produce certain molecules which nourishes the sperms.
The Sertoli cells act as a barrier between the testis and blood and secrete enzymes like inhibin. They eliminate the apoptotic germ cells and also produce seminiferous fluid to nourish the sperm. They do not play any role in primary spermatocytes.
Thus, Option-B is the correct answer.
<span>The interactions
between the mRNA codons and the tRNA anticodons
codes for a specific amino acid is by, it is the job of the tRNA to
start working after the mRNA has able to have its own complementary copy. The
mRNA will undergo to the nucleus and will move out, in order to go the rrna.
The three nucleotides codes the specific amino acid of the trna. The trna and
the mrna will be matched, it will now release the amino acid in the trna that
wil form a peptide bond. When the mrna is able to be decoded to form an amino
acid, it will now have the ability to break and make proteins in different
structures.</span>
