Question

6.

Which of the following BEST describes the function of mRNA?
A.it stays in the nucleus and is copied by DNA
B.it carries amino acids to the growing polypeptide chain
C.it makes up the ribosomes and provides the site for protein synthesis
D.it is transcribed from the DNA and carries the information to the ribosome

Answer 1

D.it is transcribed from the DNA and carries the information to the ribosome

Step-by-step explanation:

Answer Breakdown

• Choice D is the best answer. mRNA or messenger RNA transfers genetic information from genes to ribosomes to synthesize proteins.
• Choice A is incorrect. hnRNA or the pre-mRNA transcript stays in the nucleus and is copied by DNA. These kinds of mRNA serve as precursors for mRNAs and other types of RNA.
• Choice B is incorrect. tRNA or transfer RNA carries amino acids to the growing polypeptide chain.
• Choice C is not the best answer. rRNA or ribosomal RNA makes up the ribosomes and provides the site for protein synthesis
