Question

Read the following passage and answer the questions that follow: Passage: Generally, in eukaryotic cells the average length of a transcription unit along a DNA molecule is about 8,000 nucleotides, so the RNA product of the transcription is also that long. But it only takes about 1200 nucleotides from the above RNA product to translate average sized polypeptide of 400 Amino acids. (a) Name this RNA product transcribed from the DNA that subsequently translates into a polypeptide of 400 amino acids. Mention the enzyme responsible for transcribing this type of RNA from the DNA.

Hint:

mRNA is the template for protein synthesis in the process of translation.

Answer 1

The RNA product is mRNA (messenger RNA). Enzyme responsible: RNA polymerase II.
