Question

Which of the following statements is false?

A. The “TATA box’ is a type of cis-regulatory element

B. The enhancer is a type of cis-regulatory element

C. A transcription factor only binds the cis-regulatory element that regulates its own expression

D. One transcription factor can regulate genes located on different chromosomes

Answer 1

Out of all the given options, one that is found to be wrong is that a transcription factor only binds the cis-regulatory element that regulates its own expression. It is because the cis-regulatory elements are non-coding DNA, which bind to transcription factors to regulate gene expression. A single transcription factor can bind to many cis-regulatory elements, which can regulate the expression of many genes and not oneselves.

Hence, the correct option is (C).

About the incorrect options-

(A), (B), and (C)- These statements are correct regarding TATA box, enhancers, and transcription factors.

Hope it helps, Good luck !!!!
