Detailed explanation-1: -DNA replicates in the S phase of the cell cycle and initiates at specific regions in the DNA sequence known as DNA replication ‘origins’. A number of proteins participate in DNA replication and the process is subject to scrutiny by cell surveillance mechanisms called cell cycle checkpoints.
Detailed explanation-2: -Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.
Detailed explanation-3: -DNA replication is the process by which the genome’s DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own complete genome.
Detailed explanation-4: -DNA replication is called semiconservative because an existing DNA strand is used to create a new strand. Explanation. DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new complementary nucleotides are added on the two separated strands.
Detailed explanation-5: -DNA replicates by a semi-conservative method in which each of the two parental DNA strands act as a template for new DNA to be synthesized. After replication, each DNA has one parental or “old” strand, and one daughter or “new” strand. Errors made during replication are typically repaired.
