which occurs during both dna replication and protein production?\nrna leaves the nucleus.\ndna leaves the nucleus.\nrna unzips.\ndna unzips.
Answer
Brief Explanations:
- RNA leaves the nucleus: Only occurs during protein production (translation). RNA (mRNA) is made in the nucleus during transcription and then exits to the cytoplasm for translation.
- DNA leaves the nucleus: DNA remains in the nucleus in eukaryotic cells. It does not leave during either DNA replication or protein production.
- RNA unzips: RNA is usually single - stranded. While some RNA molecules can form secondary structures, the concept of "unzipping" like DNA (which is double - stranded) is not a common or accurate description for RNA in the context of these processes.
- DNA unzips: In DNA replication, the double - stranded DNA unzips so that each strand can serve as a template for new strand synthesis. In protein production (transcription, which is the first step of protein production), the DNA also unzips at the gene region being transcribed so that RNA polymerase can synthesize mRNA.
Answer:
DNA unzips.
