What is the function of ribosomes (also known as ribosomal RNA) in protein synthesis?
A. Serves as an adaptor molecule able to transport a specific amino acid to the site of protein synthesis (peptide chain elongation) in the correct sequence
B. Serves as the coordinator molecule to allow proper reading of the mRNA and placement of the correct amino acid in the sequence by the tRNAs
C. Allows interpretation of the two strands of DNA to determine which is the "sense" strand and which is the "antisense" strand
D. Allows further processing of synthesized proteins (post-translational modification) in order to ensure that the final product is physiologically active
B
Ribosomes are present in the cytoplasm and uncover the codons on the mRNA so that the correct amino acids are placed into newly synthesized protein chains.
