What would happen in a cell that completely lacked aminoacyl-tRNA synthetases?
A) No charged tRNAs would be present in the cell.
B) Transcription would initiate,but elongation would not occur.
C) Translation would be initiated,but elongation would not occur.
D) Peptide elongation would occur,but termination would not occur.
E) RNA elongation would occur,but termination would not occur.

Question

Quizplus · Accepted Answer

Aminoacyl-tRNA synthetases are responsible for attaching the appropriate amino acid to tRNA molecules. Without them, tRNAs would not be charged and therefore unable to participate in translation. This would result in a lack of protein synthesis in the cell. The other options are incorrect because they suggest that some aspect of protein synthesis could still occur, which is not possible without charged tRNAs.
