Question

which of the following types of rna are not matched correctly with their function? a trna - carries amino acids b rrna - site of protein synthesis c trna - contains the code from dna to make a polypeptide d mrna - contains the code from dna to make a polypeptide

Explanation:

• Option A: tRNA (transfer RNA) does carry amino acids to the ribosome during protein synthesis, so this match is correct.
• Option B: rRNA (ribosomal RNA) is a major component of ribosomes, which are the sites of protein synthesis, so this match is correct.
• Option C: tRNA's role is to carry amino acids and recognize codons on mRNA, not to contain the code from DNA to make a polypeptide. The molecule that contains the DNA - derived code for making a polypeptide is mRNA (messenger RNA). So this match is incorrect.
• Option D: mRNA is transcribed from DNA and carries the genetic code (in the form of codons) that is used to synthesize a polypeptide, so this match is correct.

Answer:

C. tRNA - contains the code from DNA to make a polypeptide
