NEET PG DENTAL EXAM

Detailed explanation-1: -S phase is the period during which DNA replication occurs.

Detailed explanation-2: -Most prominently, DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand. DNA replication occurs during the S-stage of interphase. DNA replication (DNA amplification) can also be performed in vitro (artificially, outside a cell).

Detailed explanation-3: -During the G1 period of interphase, the cell grows and produces many protein products to replicate organelles. G1 is followed by the S phase, during which DNA replication occurs. This is followed by the G2 phase, which prepares the cell for division.

Detailed explanation-4: -During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two “daughter” cells that inherit the same genetic information. This process is called chromosome segregation.
