Detailed explanation-1: -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.
Detailed explanation-2: -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-3: -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-4: -No. All the enzymes, cofactors, and substrates needed for DNA replication from initiation to elongation to termination occur in the nucleus. The nucleus functions to house the DNA, and in eukaryotes, the DNA does not ever leave the nucleus during replication or for any other reason.
