Answer:
B. Ribosome
Explanation:
Ribosomes are the organelles that serve as a site for protein synthesis. Each ribosome has two subunits. The small subunit first joins with mRNA and the initiator tRNA to start the process of protein synthesis. The large subunit joins the complex and the proteins are synthesized according to the nucleotide sequence of the mRNA read in the form of genetic triplets. Ribosomes are present in cytosol as well as on the surface of the rough endoplasmic reticulum of a eukaryotic cell. In both locations, they are involved in the process of protein synthesis.
