Which of the following is true of TATA boxes?
A) they are found within the core sequence of a gene regulatory sequence
B) they are found downstream of the gene being transcribed
C) they represent an area of DNA more easily opened than other areas
D) a and c are true
E) a, b, and c are true

Question

Quizplus · Accepted Answer

TATA boxes are found within the core sequence of a gene regulatory sequence, but not necessarily downstream of the gene being transcribed. They represent an area of DNA that is more easily opened than other areas, due to their high AT content, which requires less energy to break the hydrogen bonds holding the double helix together. Therefore, statements A and C are true, but statement B is not.
