What is the function of ribosomes (also known as ribosomal RNA) in protein synthesis?
A)Allow interpretation of the two strands of DNA to determine which is the "sense" strand and which is the "antisense" strand
B)Serve as the coordinator mechanism to allow proper reading of the mRNA and placement of the correct amino acid in the sequence by the tRNAs
C)Allow further processing of synthesized proteins (posttranslational modification) in order to ensure that the final product is physiologically active
D)Serve as transport molecules able to move a specific amino acid to the site of protein synthesis (peptide chain elongation) in the correct sequence

A ribosome is a cytoplasmic adapter molecule containing a complex of proteins and some RNA that essentially decodes the mRNA and places the proper individual amino acid into the growing peptide chain during protein synthesis. It does not have anything to do with double-stranded DNA, nor does it perform any posttranslational modification. The transport molecules are the transfer RNAs (tRNAs), not the ribosomes.
