Question
[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
DNA replication is reductive, because half the total DNA present is copied.
|
|
|
DNA replication is semi-conservative, because each DNA strand serves as a template during replication.
|
|
|
DNA replication is dispersive, because the two resulting DNA molecules are mixtures of parent and daughter DNA.
|
|
|
DNA replication is conservative, because one resulting molecule is identical to the original and the other consists of two new strands.

Detailed explanation-1: -So here, our correct answer for the first question will be the option be that DNA is a semi conservative for DNA replication is semi conservative because each DNA strand serve as a template during replication.
Detailed explanation-2: -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-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 result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
Detailed explanation-5: -So, the correct answer is ‘Each strand of the original, double stranded DNA molecule serves as a template for a newly constructed, complementary strand’
