During transcription, an RNA molecule is formed whose length varies depending on the size of the gene being copied. Which RNA is this?
Q1. During transcription, an RNA molecule is formed whose length varies depending on the size of the gene being copied. Which RNA is this?
Answer: mRNA
Explanation: mRNA length is directly proportional to the gene size; tRNA has a fixed small size (75-90 nucleotides) regardless of the protein.
