|
|
DNA replication occurs at an extremely slow rate.
|
|
|
DNA replication only duplicates nucleotides in pairs.
|
|
|
Each replicated strand of DNA is an old strand paired with a new strand.
|
|
|
Each replicated strand of DNA is an identical match with novariations.

Detailed explanation-1: -DNA replication is said to be semi-conservative because of the process of replication, where the resulting double helix is composed of both an old strand and a new strand. Each strand of the double helix DNA would serve as a template for synthesis of a new strand.
Detailed explanation-2: -DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the original parental helical strands.
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: -Semi-conservative replication means that during DNA replication, the two strands of nucleotides separate. Both strands then form the template for free nucleotides to bind to to create the two identical daughter strands. Hence each daughter strand has half of the DNA from the original strand and half newly-formed DNA.
