    Double stranded DNA isolated from a bacteriophage has a molecular weight of 2.1x10E8 Da.

    (1) Using this information, how many amino acids would this DNA encode?

    (2) How many different proteins could be encoded by this DNA, if the protein molecular weight is 69 kDa?

    These ideas are depicted.

    Each amino acid is encoded by a "triplet", or three nucleotides.

    First calculate the number of nucleotide pairs in the bacteriophage DNA. The average molecular weight of a pair of dexoynucleotides is approximately 618 Da. Therefore, the number of nucleotide ...
