Answered by ehtishamm

Answer:

By doing this, the DNA is more accessible and leads to moretranscription factors being able to reach the DNA. Thus, acetylationof histones is known to increase the expression of genes throughtranscription activation. Deacetylation performed by HDAC molecules has the opposite effect.
