    A few steps involved in polypeptide synthesis are given below. In which of them, the /-RNA participates?
    1. Activation ofamino acids.
    2. Elongation of polypeptide chain
    3. Translocation
    4. Transcription
    Identify the correct combination:

    A)  only 1, 3 and 4                 

    B)  only 2, 3 and 4

    C)  only 1, 2 and 4
