Results in the remodeling of chromatin that can activate or inhibit gene expression

Explanation:

Alteration of histones by addition of methyl and acetyl groups are examples of chromatin remodeling complexes. These allows for the remodeling /alteration of the chromatin state to allow transcriptional machinery and other cellular processes to have access to the DNA. This way, they can either activate or inhibit gene expression. Methylation patterns inhibits gene expression while acetylation activates gene expression and so on.

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…
