Respuesta :
DNA undergoes semi conservative DNA replication in which a new Daughter strand is evolved from each parent DNA strand. Hence it is important that the parent DNA strand separate such that bases on the Daughter DNA can be complimentary to that of the parent strand it is coded from and same as that of the antiparallel parent DNA which is being separated. This ensures conservation and protection of the integrity of the genetic code
Replication is the process of central dogma in which the parent strands replicates and double to produce complementary daughter strands.
The process of replication involves enzymes that break and separates the double-helical strands of the DNA and the hydrogen bonds between the purines and pyrimidines of the antiparallel strands are broken.
In the DNA strand, there are four types of nitrogenous bases that are adenine, guanine, thymine and cytosine which codes for the genetic information.
So, for the parent strand to undergo replication the separation of strands are necessary as the bases in daughter strands are formed from the complementary pairing to the parent strand.
The complementary pairing of the daughter strand ensures semi-conservative strand formation.
