Translation of an mRNA transcript generates numerous polypeptide chains.The accumulation of these polypeptide chains is faster than can be accounted for when considering the rate of ribosomal-mediated translation of mRNA transcripts.What accounts for this discrepancy?
A) The process cannot be accurately measured.
B) There are multiple mRNA transcripts per ribosome.
C) mRNA transcripts are translated by polysomes.
D) Each tRNA binds multiple ribosomes at the same time.
E) Some tRNAs bind inosine.

Question

Quizplus · Accepted Answer

mRNA transcripts are translated by polysomes, which means that multiple ribosomes can simultaneously translate a single mRNA transcript. This leads to multiple polypeptide chains being generated simultaneously, increasing the overall rate of protein synthesis.
