  • The RNA product is mRNA (messenger RNA), because it carries the genetic code from DNA to ribosomes for protein synthesis.

  • Since one amino acid is coded by a codon of three nucleotides, a polypeptide of 400 amino acids requires an mRNA with at least 400×3=1200400 \times 3 = 1200400×3=1200 nucleotides (excluding stop codon and UTRs).

  • The enzyme responsible for its transcription is RNA polymerase II.

Final Answer: The RNA product is mRNA, which translates into a polypeptide of 400 amino acids. It is transcribed from DNA by the enzyme RNA polymerase II.
