Question

if during replication,each daughter DNA duplex retains half of the parental DNA ,such method is called ..type of replication​

Answer 1

Explanation:

Since DNA strands run anti-parallel, the 3' to 5' template strand will be continuously replicated and is known as the leading strand.

Answer 2

This method is called semi-conservative mode of DNA replication.

• Meselson and Stahl proved the semi-conservative mode of DNA replication.They experimented with $N$$_{15}$ and$N_{14}$ and through a series of experiments of E.coli they proved that the DNA replication was semi conservative.
• In this method of DNA replication the daughter DNA consists of one old (parental) DNA and one new DNA strand.
• The new strands are complementary to the old strand and the genetic material is equally divided in both daughter cells.
• Thus, due to this method the original genetic material can be passed down generations thereby exhibiting semi conservative mode of DNA replication.
