Question

Which of the following terms associated with transcription describe regions of nucleic acid? Select all that apply.

1) Promoter
2) Gene
3) Terminator
4) RNA Polymerase

Answer 1

In the context of transcription, 'promoter', 'gene', and 'terminator' are terms that describe regions of nucleic acid. RNA Polymerase, while essential to the process, is an enzyme, not a region of nucleic acid.

Step-by-step explanation:

Understanding Transcription in Biology

The process of transcription involves converting a DNA sequence into RNA. During this process, regions such as the promoter, the gene, and the terminator are critical components associated with the DNA template. Firstly, initiation occurs when RNA polymerase, an enzyme, binds to the promoter region. This event marks the beginning of transcription. As RNA polymerase moves along the DNA, it reads the nucleotide sequence and starts adding nucleotides to form an mRNA strand in a phase called elongation. Finally, when RNA polymerase reaches the terminator region, it signals the end of transcription, resulting in the completion of the mRNA transcript.

Therefore, the terms that describe regions of nucleic acid associated with transcription are:

• Promoter
• Gene
• Terminator

Note that RNA Polymerase is an enzyme involved in the process, but it is itself not a region of nucleic acid.
