    Ribosomes are the centre for

    A)  Respiration       

    B)  photosynthesis

    C)  Protein synthesis

    D)  fat synthesis

    Correct Answer: C

    Solution :

    [c] Ribosomes are the workhouses of protein biosynthesis, the process of translating messenger RNA (mRNA) into protein. The mRNA comprises a series of codons that dictate to the ribosome the sequence of the amino acids needed to make the protein. Using the mRNA as a template, the ribosome translates each codon of the mRNA, pairing it with the appropriate amino acid. This is done using molecules of transfer RNA (tRNA) containing a complementary anticodon on one end and the appropriate amino acid on the other.
