Answer: The correct answer is -
B) amino acid.
Explanation:
Protein synthesis is a two step process, which includes transcription (conversion of DNA to mRNA) and translation (mRNA to protien).
During the process of translation, tRNA (transfer RNA) molecule carries specific amino acid at the ribosome site according to the codon (a sequence of three nucleotides that code for particular amino acid) sequence present in the mRNA (messenger RNA) .
In this way, a chain of amino acid is assembled, giving rise to particular protien.
Thus, option B) is the right answer.
