E) aminoacyl synthetase

Question

Quizplus · Accepted Answer

Transcription in eukaryotes requires several transcription factors that bind to specific sequences in the promoter region of a gene and help RNA polymerase to initiate transcription. These transcription factors recruit RNA polymerase and help in the formation of the transcription initiation complex. Other factors, such as enhancers and silencers, may also be involved in regulating gene expression during transcription. While start and stop codons, ribosomes, tRNA, and aminoacyl synthetase are necessary for translation, they are not required for transcription. The protein product of the promoter is also not necessary for transcription, as it is only produced after transcription and translation have occurred.
