Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What do we call DNA replication since new DNA has 1 parent strand and 1 new strand?
A
Conservative
B
Semiconservative
C
Dispersive
D
None of the above
Explanation: 

Detailed explanation-1: -Thus after every round of replication, there are two DNA molecules produced where each of them have a single parental and a newly synthesized strand. Since only one out of the two parents is conserved between the two strands, it is called semiconservative DNA replication.

Detailed explanation-2: -Each new double strand consists of one parental strand and one new daughter strand. This is known as semiconservative replication.

Detailed explanation-3: -DNA replication is semiconservative, meaning that each strand in the DNA double helix acts as a template for the synthesis of a new, complementary strand. This process takes us from one starting molecule to two “daughter” molecules, with each newly formed double helix containing one new and one old strand.

Detailed explanation-4: -The semi-conservative method of replication suggests that the two parental DNA strands serve as a template for new DNA and after replication, each double-stranded DNA contains one strand from the parental DNA and one new (daughter) strand.

Detailed explanation-5: -The leading strand is the strand of new DNA which is synthesized in the same direction as the growing replication fork.
