Multiple Choice
In the context of the central dogma, what is the primary role of mRNA in protein synthesis?
A
It delivers specific amino acids to the ribosome by matching anticodons to codons on the message.
B
It stores hereditary information in the nucleus and replicates to pass genetic information to daughter cells.
C
It carries the genetic code transcribed from DNA to the ribosome, where it serves as the template for translating a polypeptide.
D
It forms the catalytic core of the ribosome and catalyzes peptide bond formation during elongation.
Verified step by step guidance1
Understand the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein.
Recognize that mRNA (messenger RNA) is synthesized during transcription, where it carries the genetic code copied from DNA.
Identify that the primary role of mRNA is to serve as a template for protein synthesis by providing the sequence of codons that determine the order of amino acids in a polypeptide chain.
Distinguish mRNA's function from other RNA types: tRNA delivers amino acids, rRNA forms the ribosome's core and catalyzes peptide bonds, and DNA stores hereditary information.
Conclude that mRNA's main role is to carry the genetic information from the nucleus to the ribosome, enabling translation and protein assembly.
