Detailed explanation-1: -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.
Detailed explanation-2: -The correct answer is (D) RNA primase makes the RNA primer, while DNA Pol epsilon extends that primer with DNA. DNA polymerase epsilon is the enzyme that synthesizes new strands of DNA during replication.
Detailed explanation-3: -Definition. 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: -A chromatid is one of the two identical halves of a chromosome that has been replicated in preparation for cell division. The two “sister” chromatids are joined at a constricted region of the chromosome called the centromere.
