If you block histone deacetylase, what effect would you expect to see on transcriptional activity?.

1 answer:

8 0

Histone deacetylase is responsible for removing the acetyl group from the histone 3 lysine 9 residue. Remember that deacetylation is one step in converting euchromatin to heterochromatin. Because euchromatin is transcriptionally active (transcriptional machinery is able to reach gene of interest), and blocking histone deacetylase activity would result in an the DNA remaining as euchromatin, we would expect to see an increase in transcriptional activity.

So there’s your answer: An increase in transcriptional activity.

A) rapidly increase.

B) rapidly decline.

C) gradually increase.

D) gradually decline.

E) remain unchanged.

The CORRECT ANSWER IS D)

D) gradually decline.

Explanation:

It will decline gradually. The causative factor for the natural deterioration is not shown when only mature adults are kept. The most apparent and favourable use of slot limits. The average median is notably observed when younger ones experience natural deterioration, middle ones are plucked with the majority of the mature ones continuing to be preserved.

In situation where the longer ones are left in captivity slowly, they tend to show more caring capacity, while those who are not kept in captivity will continue heavily and results to a reduction in length, but gradually.

Elis [28]

Answer:

c. Brownian ratchet

Explanation:

Mitochondria are cell organelles. They are known as the power house of the cells. The energy needed to power the cell is generated by the mitochondria. They functions like a digestive system.

The mitochondria chaperone are proteins that helps the proteins along pathways for their folding. They shield the proteins from other proteins and protect them from binding the folding process. The chaperone are mainly concern with the folding of protein.

The chaperone acts as a Brownian ratchet as the mitochondrial chaperone guides the matrix protein into matrix by the biased diffusion process.
