Answer:
The correct answer is "Histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction".
Explanation:
Histone acetyltransferases (HATs) are regulators of gene activation and deactivation, achieved by the transference of an acetyl group from acetyl-CoA to histones. HATs function by the premise that histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction. Therefore, most of the times histone acetylation increases gene expression, because the acetylated gene is free from the histones and is able to be encoded.

Explanation:
Diabetes is a serious health condition that impacts the way our body assimilates sugar, which is an important energy source for our body. Different field of studies have come up with reports suggesting that poor dietary habits and some sort of inactivity could trigger the onset of the disease.
In order to maintain the required healthy lifestyle to keep the disease away, people are required to eat healthy foods, devoid of too much fats and calories but must be rich in fibre. There should also be between 30 – 60 minutes of moderate physical activity. If one is also overweight, 5-10 percent of the body weight can be removed to reduce the risk of the disease.
