Which molecule is transcribed from DNA?

Which molecule is transcribed from DNA?

• A. Lipid
• B. DNA
• C. Protein
• D. RNA

Answer: (D)

Transcription copies genetic information from DNA into RNA. RNA polymerase reads a gene on DNA and builds a complementary RNA strand in the 5′ to 3′ direction, using DNA as the template. The product is RNA, which can be messenger RNA, ribosomal RNA, or transfer RNA, depending on the gene. Lipids aren’t produced by transcription; they’re made through metabolic pathways. DNA isn’t the product of transcription, since replication copies DNA. Proteins are made later by translating the RNA, not by transcription itself.
