DNA replication is semiconservative as

A

Only ninparent strand acts as template

B

Both strands of new molecule are synthesized de nova

C

One of the strand ineach new molecule is parental and the other in new

D

Daughter strands are dispersive.

Text Solution

Verified by Experts

The correct Answer is:
C
DNA replication is semiconservative as one of the strand in each new molecule is parental and the other is new.

  • The semi-conservative nature of DNA replication was established by Meselson and Stahl in their classic experiment with bacteria. They grew bacteria in N^(15)-NH_(4)CI containing medium with N_(14) - containing compounds and allowed to grow for three generation . CsCI density gradient centrifugation of isolated DNA established the nature of semiconservation DNA replication. The pictorial representation below shows the positon of differentially labeled DNA in CsCI density gradient. Had the DNA replication been conservative, what would have been the pattern ?

    A
    B
    C
    D
