Which process copies genetic information from DNA to RNA?

• A. Replication
• B. Translation
• C. Transcription
• D. Splicing

Answer: (C)

Transcription is the process that copies genetic information from DNA to RNA. In transcription, RNA polymerase binds to a DNA promoter, reads the template strand, and assembles a complementary RNA strand in the 5' to 3' direction using ribonucleotides (A pairs with U, C with G). The resulting RNA can be mRNA, rRNA, or tRNA, with mRNA carrying the code to make proteins. This step transfers the information encoded in DNA into an RNA form that can be used for protein synthesis or other roles. By contrast, replication duplicates DNA into DNA, translation uses RNA to build proteins, and splicing is the processing of pre-mRNA after transcription.
