DNA replication is said to be 'semi-conservative' because the two new daughter DNA molecules are "Half old" and "Half new". Half the original DNA molecule is saved, or conserved in the daughter molecules.
The best objective to describe DNA replication is to understand the process by which a cell makes an identical copy of its DNA. This includes grasping the role of enzymes like DNA polymerase, the significance of semi-conservative replication, and the importance of fidelity to maintain genetic information.
Semiconservative replication ensures genetic stability by passing on only one parental DNA strand to each daughter cell, allowing for accurate transmission of genetic information. It also allows for genetic variation through the incorporation of new mutations during the replication process.
The template for semiconservative replication is the original DNA strand that serves as a guide for creating a new complementary strand. During DNA replication, each original parental strand acts as a template for the synthesis of a new daughter strand.
Semiconservative DNA replication occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. It involves separating the DNA strands and using each strand as a template to synthesize a new complementary strand.
Conservative replication and semiconservative replication are the ways DNA reproduces itself. The difference being whether the newly formed strands pair with each other or with an old one.
Semiconservative DNA replication occurs during the S phase of the cell cycle. This is the phase where DNA is replicated before cell division. Each new DNA molecule contains one original strand and one newly synthesized strand.
Semiconservative replication means that during DNA replication, each new DNA molecule contains one original ("old") strand and one newly synthesized ("new") strand. This process ensures that the genetic information from the original DNA molecule is conserved in the newly formed molecules.
The experiment that supported the hypothesis that DNA replication was semiconservative was known as the Meselson-Stahl Experiment.
Watson and Crick mentioned it slightly in their paper but didn't propose a full method of replication. a number of different people collaborated to work out the full model of replication which is still no totaly finished, (few proteins left to find)
DNA replicates using the process called semiconservative replication. An original DNA molecule is complementary to the replicated molecule, which means that they are identical copies of each other.
semiconservative replication - original DNA double strand will unwind into 2 strands, so one original strand will serve as a template for synthesizing a new complementary strand , thus forming a new DNA (one with old strand and one with a new strand)
DNA replication is semiconservative because each new double helix contains (1) old and (1) new strand. each mother strand serves as a template for a new strand.The two strands are complementary, but not identical.
