Protein synthesis requires the use of mRNA, which
A) is made in the nucleolus.
B) must be made by the ribosomes.
C) is translated by the ribosomes into the amino acid sequences of proteins.
D) carries the message to the nucleus to synthesize new DNA during cell division.

Question

Quizplus · Accepted Answer

mRNA carries the genetic information from DNA in the nucleus to ribosomes in the cytoplasm where it is translated into the amino acid sequence of proteins through the process of protein synthesis. Option A is incorrect because the mRNA is transcribed in the nucleus not the nucleolus. Option B is incorrect because the ribosomes translate the mRNA not make it. Option D is incorrect because mRNA does not carry messages to the nucleus for DNA synthesis.
