How many diff polypeptides

  1. Jan 17, 2005 #1
    how many diff polypeptides, each composed of 5 amino acids, could be synthesized using the 20 common amino acids?

    the answer is simply 20^5 right?

    if not, then can u please tell me what im doing wrong thx

    theoretically yes 20^5, but some of them may be difficult to synthesize
