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. The synthesis phase of the interphase is known as the S phase.
Detailed explanation-2: -Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. DNA replication always occurs in the nucleus. Eukaryotic DNA replication involves more polymerases than prokaryotic replication.
Detailed explanation-3: -DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region of prokaryotic cells. Eukaryotic cells are cells that have a nucleus and membrane bound organelles, such as plant cells and animal cells. Eukaryotic cells contain their DNA in the nucleus, and thus this is where DNA replication occurs.
Detailed explanation-4: -In eukaryotes, as DNA is present inside the nucleus, DNA replication takes place inside the nucleus. Whereas in Prokaryotes, no well-developed nucleus is found. Also, no nuclear separation is seen due to the lack of a nuclear membrane. Hence, in prokaryotes, cytoplasm occurs.
