DNA replication is defined as?

• A. Transcribing DNA into RNA
• B. Replicating proteins
• C. Translating RNA into protein
• D. The process of copying DNA to create identical strands; occurs in the nucleus

Answer: (D)

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division. It involves unwinding the double helix and using each original strand as a template to synthesize a new complementary strand, resulting in two identical DNA molecules (semi-conservative replication: each new molecule has one old and one new strand). In eukaryotic cells, this copying occurs in the nucleus. This is distinct from transcription, which makes RNA from DNA, and translation, which builds protein from RNA. So the best description is the process of copying DNA to create identical strands, occurring in the nucleus.
