lesantik [10]

Answer:

The correct answer is A) Histone deacetylation generally decreases gene expression.

Explanation:

Histones are the proteins that are responsible for the condensation of chromatin, which is directly linked to the capacity that a gene has to be expressed. The more condensed a gene is, the less expressible it becomes.

In order to regulate the gene expression, histones can suffer from many modifications that can change their conformation and the expressiveness of specific genes.

<u>Histone acetylation is linked with an increase of gene expression; while deacetylation and methylation decrease gene expression.</u>

Semisolid media such as MIO are used to determine motility. Another such medium such is SIM (sulfide, indole, motility) medium.
Flauer [41]

Answer:

Explanation:

In this specific scenario, seeing since both of the mediums are differential, the bacteria can grow on either of them, therefore either of them would be a good choice. A differential media allows the researcher to visually distinguish which species have the specific biochemical process. Which in this case both options have the ability to allow bacteria to grow which is what is needed.
