Which of the following terms associated with transcription describe regions of nucleic acid?

Select all that apply:

A. Terminator

B. Promoter

C. RNA polymerase

D. Gene

Answer

The terms from the query that describe regions of nucleic acid are:

A. Terminator

B. Promoter

D. Gene

Explanation:

A. Terminator: This is a sequence of nucleic acid that signals the end of transcription for a gene. It defines where RNA polymerase should stop transcribing, and thus it is a specific region of the nucleic acid.

B. Promoter: This is a region of DNA that initiates transcription of a particular gene. It serves as the binding site for RNA polymerase and other transcription factors, making it another specific region of nucleic acid.

C. RNA polymerase: This is an enzyme that synthesizes RNA from a DNA template during transcription. It is not a region of nucleic acid but rather a protein that interacts with nucleic acids.

D. Gene: A gene is a segment of nucleic acid that encodes a functional product, usually a protein. It represents a specific region of nucleic acid that carries the information for biological function.

Thus, the correct answers are A (Terminator), B (Promoter), and D (Gene) as they refer to specific regions of nucleic acid.
