The histone proteins are among the most slowly evolving proteins. For example, a histone protein called histone H4 in cows and p

juin [17]

The statement is true, histones are proteins that are high in the amino acids lysine and arginine, making them extremely basic in their structure.

Histones control the degree of packaging of DNA during the processes of gene expression, replication or repair of hereditary material, among many others.

Histones H2A, H2B, H3 and H4 are small and basic proteins that are highly conserved in evolution and are composed of a globular domain at the carboxy-end, and by regions known as "tails", which are found at the amino-terminal end.

These tails are high in the amino acids lysine and arginine, which give them a positive charge.

This region is the site of numerous post-translational modifications that, it has been proposed, would modify the histone charge, altering the accessibility of the DNA and the protein / protein interactions with the nucleosome.

Chromatin compaction occurs due to the interaction between the negative charges of DNA and the positive charges of amino acids, mainly located on the tails of histones H3 and H4.

Therefore, we can conclude that the modifications on the amino acids lysine and arginine that form the basic part of the histone structure alter their functions.

Following a meal glucose must move from the gut lumen where there is a high glucose concentration into the intestinal cell where

Alchen [17]

This movement from a high concentration area to a low concentration are is called Active transport.

<h3>Active Transport</h3>

Active transport by definition is a process that is characterized by the movement of molecules against a concentration gradient. Additionally, this process requires energy.

As in the question above, glucose molecules have to be moved across the gut lumen of higher glucose concentration to the intestinal cells of relatively low level of glucose.

Adenine methylase is an enzyme used during mismatch repair (MMR). It helps determine which strand needs to be repaired by discri

I am Lyosha [343]

Answer:

The correct answer would be - MMR would be hindered because both strands would be unmethylated and both would appear as new DNA strands and it would not be able to determine which strand has the error .

Explanation:

In gene expression or DNA replication, the enzyme responsible for the synthesis of DNA from nucleoside triphosphate causes errors sometimes such as mismatch base pair that result in a change in genetic makeup.

For MMR, the DNA template and the strand formed required easily to be differentiated. As the newly synthesized strand is unmethylated and the DNA template strand is methylated results in DNA remain hemimethylated for a very short period.

After MMR, DNA adenine methylase enzyme that transfers a methyl group to the adenine of the sequence 5'-GATC-3' daughter strand formed.

Mutated DAM or DNA adenine methylase will not be able to transfer methyl group which leaves both template and daughter strands unmethylated and mismatch repair would be hindered as it will not be able to identify.
