Proteins that bind to DNA and influence the rate at which particular structural genes will be expressed are called
A) transcription factors.
B) autosomes.
C) enhancers.
D) sex-linked traits.
E) mutations.

Question

Quizplus · Accepted Answer

Proteins that bind to DNA and influence gene expression are known as transcription factors. They regulate transcription by binding to a specific DNA sequence and either promoting or inhibiting the recruitment of RNA polymerase to that gene. Therefore, option A – transcription factors would be the best choice. Option B (autosomes) and option D (sex-linked traits) are not related to gene expression regulation. Option C (enhancers) refers to a specific type of DNA sequence that can bind transcription factors and increase the rate of transcription, making it a close option, but not as broad as option A. Option E (mutations) refers to changes in DNA sequences that can affect gene expression, but not a protein that binds DNA and influences gene expression.
