LIFE SCIENCE

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.

Detailed explanation-2: -DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.

Detailed explanation-3: -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.
