Which of the following most accurately describes the steps involved in protein synthesis?
A) Transcription factors activate promoter region → translation by ribosomes → transcription by mRNA
B) Transcription factors activate promoter region → transcription by mRNA → translation by ribosomes
C) Translation by ribosomes → transcription factors activate promoter region → transcription by mRNA
D) Transcription by mRNA → transcription factors activate promoter region → translation by ribosomes

Question

Quizplus · Accepted Answer

The steps involved in protein synthesis are transcription and translation. Transcription involves the synthesis of messenger RNA (mRNA) from a DNA template. Transcription factors bind to specific DNA sequences called promoter regions to initiate transcription. The mRNA molecule then undergoes translation, which involves the synthesis of a protein from the mRNA template. Ribosomes are responsible for the translation process. Therefore, the correct sequence of events is transcription by mRNA followed by translation by ribosomes. Choice B accurately describes this sequence of events.
