Which of the following results is most likely to occur if acetylation of histone tails in the chromatin of embryonic cells is increased?
A) increased chromatin condensation

C) decreased binding of transcription factors
D) inactivation of the selected genes

Question

Quizplus · Accepted Answer

Acetylation of histone tails generally leads to a decrease in chromatin condensation. This modification reduces the positive charge on histones, weakening their interaction with the negatively charged DNA. As a result, the chromatin becomes more open or relaxed, making the DNA more accessible for transcription and other processes.
