    Answer: Histones, DNA methylation

    Explanation:

    The double stranded DNA are wrapped twice around a histone protein and depending on how loosely or tightly DNA are wounded around histion, DNA can be either read or not. The nature of histones have the ability to control which sections of DNA get copied and expressed. Histone synthesis stops when DNA synthesis ceases, histone are modified by acetylation, methylation ADP--ribosylation and phosphorylation. It has shown that environmental factors such as diet can have an effect on protein structure. Alteration of the histone protein structure can affect the expression of some genes.

    DNA methylation can also inhibit the expression of some genes, which can be caused by environmental factit's.
