Knowledge Check

  • The proof for semiconservative mode of DNA replication was First provided by Matthew Meselson and Franklin Stahl. Escherichia coli were the first organism to be used for this experiment and then it was done in with higher organisms such as plants and human cells. The process of DNA replication in terms of energy is a very expensive process. It involves the formation of a replication fork. Given below is a graph showing the percentage of Adenine in two different double stranded DNA. Meselson and Stahl provided confirmation to whose model of DNA?

    A
    Linus Pauling
    B
    Johann Friedrich Miescher
    C
    Watson and Crick
    D
    None of these

Given below is a graph showing the percentage of Adenine in two different double stranded DNA. DNA replication is often termed as a semi-discontinuous process because:

    A
    Formation of a primer strand takes place during replication of DNA.
    B
    Helicase unwinds the helix in phases
    C
    Okazaki fragments are formed during DNA replication.
