According to the provided text and Figure 5.22, which of the following best describes the flow of genetic information in a eukaryotic cell and the key cellular locations involved?

  • A: DNA replication in the nucleus, followed by protein synthesis in the cytoplasm.
  • B: DNA to RNA in the nucleus, and then RNA to protein in the cytoplasm.
  • C: RNA synthesis in the cytoplasm, followed by protein synthesis in the nucleus.
  • D: Protein synthesis in the nucleus, followed by DNA replication in the cytoplasm.

Explanation

Figure 5.22 and the accompanying text illustrate that gene expression involves DNA dictating mRNA synthesis in the nucleus, followed by mRNA moving to the cytoplasm where ribosomes translate it into protein.
