Transcription is defined as which of the following?

• A. The process where the DNA sequence in a gene is copied into mRNA
• B. The process where mRNA is translated into protein
• C. The process of replicating DNA
• D. The process of splicing RNA

Answer: (A)

Transcription is the process by which a gene’s DNA sequence is copied into an RNA molecule, mainly messenger RNA. This step uses RNA polymerase to read the DNA template and synthesize an RNA strand that mirrors the gene’s information (replacing thymine with uracil). In eukaryotes, this initial RNA (pre-mRNA) is then processed to become mature mRNA, including splicing to remove introns. This flow—DNA to RNA to protein—is central to how genetic information is expressed. Translation, by contrast, converts mRNA into a protein, DNA replication copies the DNA itself, and splicing is a later RNA processing step that edits the RNA after transcription.
