AP BIOLOGY

Detailed explanation-1: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. 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-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: -The nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell’s chromosomes and is the place where almost all DNA replication and RNA synthesis occurs.

Detailed explanation-4: -DNA replication occurs in the nucleus in eukaryotes, whereas in cytoplasm in prokaryotes.

Detailed explanation-5: -The final step is called translation, which involves the conversion of mRNA to protein. DNA replication and transcription occur inside the nucleus because the enzymes required to carry out these processes are found in the nucleoplasm.
