Detailed explanation-1: -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. Whereas in Prokaryotes, no well-developed nucleus is found.
Detailed explanation-2: -All RNA viruses replicate in cytoplasm, except Orthomyxoviruses and Retroviruses that have replicative stages in nuclei. All DNA viruses require a nucleus, except Poxviruses that can replicate in the cytoplasm.
Detailed explanation-3: -The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA. Each cell in your body (with the exception of germ cells) contains the complete set of your DNA. When a cell divides, the DNA must be duplicated so that the each new cell receives a full complement of DNA.
