A region of the genome encodes a protein, and thus it contains a(n)
A) transposon.
B) open reading frame.
C) microRNA gene.
D) tRNA gene.
E) enhancers.

Question

Quizplus · Accepted Answer

An open reading frame (ORF) is a sequence of DNA that encodes a protein. Therefore, a region of the genome that encodes a protein would contain an ORF.

The other options are not applicable in this scenario as:
- Transposons are mobile genetic elements that can insert themselves into different regions of the genome, but they do not directly encode proteins.
- MicroRNA genes encode non-coding RNA molecules that regulate gene expression, not proteins.
- tRNA genes encode transfer RNA molecules that are involved in protein synthesis, but they themselves are not proteins.
- Enhancers are regulatory DNA sequences that can enhance or inhibit gene expression, but they do not directly encode proteins.
