Histone deacetylase inhibitors are a class of drugs used as mood stabilizers and anti-epileptics that are also being researched for their efficacy as anti-cancer agents. Histone deacetylase inhibitors block the action of histone deacetylases, which remove acetyl groups from lysine residues in histone tails. How will blocking histone deacetylases affect gene expression in the cell?

Chromatin will become more open,and gene expression will be increased

Explanation:

The histone deactylase inhibitors are the chemical compounds that inhibits the histone deacetylases. These compounds are used as a class of drugs that is used for psychiatry and mood stabilizer. Most recently it is being used for the inflammatory disease and treatment of cancer.

In this class of drug there is an assistance of histone acetyl transferase which acetylate the lysine residues in core histones which leads to transcriptionally active and less compact chromatin.

Hence, the chromatin will be more open and gene expression is increased.

i think the answer would be d

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
