    The distance between two nucleotides in DNA is

    A)  \[34\text{ }{{A}^{o}}\]           

    B)  \[3.4\text{ }{{A}^{o}}\]

    C)  \[0.34\text{ }{{A}^{o}}\]      

    D) \[\text{20 }{{A}^{o}}\]

    Correct Answer: B

    Solution :

    : DNA is a polynucleotide chain and the distance between two consequetive nucleotides is\[3.4A{}^\circ \](0.34 nm), i.e., purines and pyrimidine bases are placed regularly along the DNA molecules at a distance of\[3.4A{}^\circ \]. This was shown by Wilkins and co-workers.
