Detailed explanation-1: -DNA is found inside the nucleus of eukaryotes. Inside the nucleus, DNA replication occurs. During the Synthesis stage of the Interphase, this DNA replication takes place.
Detailed explanation-2: -DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.
Detailed explanation-3: -DNA replication is a process of the formation of new DNA strands. DNA replication is a semi-conservative method where one new strand synthesizes on an old one. In eukaryotes, as DNA is present inside the nucleus, DNA replication takes place inside the nucleus.
Detailed explanation-4: -DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (antiparallel) directions.
