A very easy quick question

  1. Apr 20, 2007 #1
    this is a very easy question from my exam last night, i think the answer key is wrong. so tell me what you think the right answer is.

    the wild type sequence of the template strand for a peptide is

    5' - TCACCCGTAGAGCAT -3'

    Identiful the effect of the mutation:

    5' - TCACCCCTAGAGCAT - 3'

    A. one amino acid replaced by another with similar properties.
    B. one amino acid replaced by another with different properties.
    C. same primary sequence.
    D. the resulting peptide will be once amino acid shorter than the wild type.

    here's the codon table that you may need:

    You need to tell us which is your answer first. PF rules.
