DNA replication is called semiconservative because

DNA replication is called semiconservative because A) each daughter DNA consists of one new helix and one old helix. B) the parent DNA is copied over to make new daughter DNA without unwinding. C) only the new daughter cell gets the new DNA while the parent DNA stays in the old cell. D) DNA replication only occurs under conditions considered “conservative” for cell growth. E) All of the above are true

The Correct Answer and Explanation is :

DNA replication is termed “semiconservative” because each daughter DNA molecule consists of one original (parental) strand and one newly synthesized strand.his means that during replication, the two strands of the DNA double helix separate, and each serves as a template for the formation of a new complementary strand.s a result, each of the two resulting DNA molecules contains one old strand and one new strand.citeturn0search9
Explanation:

he term “semiconservative” was introduced following the groundbreaking work of scientists Matthew Meselson and Franklin Stahl in 1958.hey conducted an experiment using nitrogen isotopes to trace the replication process of DNA.heir findings demonstrated that after one round of replication, each DNA molecule consisted of one strand with the original heavy nitrogen isotope and one strand with the lighter nitrogen isotope.his observation confirmed that DNA replication is semiconservative.citeturn0search10
n contrast, the “conservative” model of DNA replication would suggest that the entire original DNA molecule remains intact, and a completely new DNA molecule is synthesized.owever, this model was ruled out by the Meselson–Stahl experiment, as it did not align with their observed results.citeturn0search10
he semiconservative nature of DNA replication is crucial for maintaining genetic fidelity across cell divisions.y preserving one original strand in each new DNA molecule, the process ensures that the genetic information is accurately transmitted to daughter cells.his mechanism also facilitates DNA repair, as the original strand can serve as a template to correct errors in the newly synthesized strand.citeturn0search9
n summary, the semiconservative model of DNA replication ensures that each new DNA molecule retains one original strand, thereby preserving the genetic information and maintaining the integrity of the genome through successive generations.
