Describe the effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases
Scrat [10]

Answer:

The effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases is that it binds to the RNA polymerases, and reduces the process of translocation which is essential for RNA synthesis that is required for RNA polymerases elongation.

Explanation:

Amanitin is a peptide that is cyclic in nature. It is repelled by water thereby making it an hydrophobic peptide.

Amanitin is a toxic peptide that is found in Amanita ( a type of mushroom).

Alpha Amanitin in particular is the one that affects the elongation rate of RNA Polymerases in the body.

When Alpha Amanitin gets into the body system, it travels straight to the liver and due to its very strong affinity for RNA polymerases, it immediately attaches itself to them.

After the attachment, Alpha Amanitin, is disturbs the bridge helix found in RNA polymerase, preventing the hindering and slowing down the proces of translocation from happening.

Once translocation is hindered, RNA is no longer synthesized. Hence, the elongation of RNA polymerases is hindered and this results in severe illness in the body such as liver failure, cytolysis of the liver

Which of the following statements about excision repair is correct?
maxonik [38]

Answer:

a. True, b. False, c.True, d. True

Explanation:

a. Base excision repair is started by a DNA glycosylase  that recognizes the changes and removes the altered base by cleavage of the glycosidic bond binding the base and the deoxyribose sugar together.

b. Nucleotide excision repair works by a cut-and patch mechanism that removes their heavy lesions, including pyrimidine dimers and nucleotides . Endonucleases are responsible for the lesion of the damaged strand.

c. Nucleotide excision repair  is initiated by the proteins namely UvrA, UvrC, and UvrB in Escherichia coli.

-UvrD (helicase II) later removes the damaged strand

-DNA polymerase I (PolI) fills in the resulting gap.

d. DNA glycolases removes the damaged nitrogenous base.

-It leaves the sugar-phosphate backbone intact and thus creating an  apurinic/apyrimidinic site, which is commonly referred to as an AP site.

e. Xeroderma pigmentosum complementation group A(XPA)

-This is an essential protein in the nucleotide excision repair pathway.

- It helps to make a pre-incision complex along with other proteins.
