Histones function as gatekeepers that loosen or tighten chromatin, and the way this occurs is that neither answer is correct histone acetylation loosens histones histone methylation generally restricts transcription both answers are correct
Sri K.
How does histone acetylation affect chromatin? It loosens the chromatin and allows increased transcription. It allows DNA to become resistant to damage. It helps the histones have a greater affinity for DNA. It inhibits DNA replication by making it more difficult to separate the DNA strands. It causes the chromatin to become more condensed in preparation for metaphase.
