Answer:
Step-by-step explanation:DNA replication happens during the cell division cycle in eukaryotic cells and adds DNA to the genome. The replication of DNA ensures that each daughter cell obtains an exact duplicate of the genetic material.
During DNA replication, the double-stranded DNA molecule unwinds and divides into two strands. Each separated strand acts as a template for the synthesis of a new complementary strand. The enzyme DNA polymerase is essential in DNA replication because it catalyzes the addition of nucleotides to the developing DNA strand.
The replication of the eukaryotic genome occurs in various stages:
Step 1: Initiation
Step 2: Elongation
Step 3:Priming
Step 4: Leading and Lagging Strands
Step 5: Fragmentation
Note: the process of adding DNA to the genome of a eukaryotic cell occurs during DNA replication, not through the direct addition of foreign DNA.
