During protein synthesis, ribosomes:
A) attach to the mRNA molecule and travel along its length to produce a polypeptide
B) attach to the DNA molecule and travel along its length to produce an mRNA molecule
C) translate mRNA into tRNA
D) transcribe DNA into mRNA
E) translate tRNA into protein

Question

Quizplus · Accepted Answer

Ribosomes attach to the mRNA molecule and travel along its length, translating the encoded information into a polypeptide chain (protein synthesis). This process is known as translation. Choices B, C, D, and E describe different processes or inaccuracies. B describes a function of RNA polymerase during transcription, not ribosomes. C and E incorrectly describe the function of ribosomes and the process of translation. D accurately describes transcription but is not a function of ribosomes.
