Which pathway is affected by an inherited mutation in the atm gene?
Katena32 [7]

The question is incomplete as it does not have the options which are:

photoreactivation

reactivation repair pathway

nucleotide excision repair pathway

UV repair pathway

p53 repair pathway

Answer:

p53 repair pathway

Explanation:

ATM gene or ataxia telangiectasia-mutated is a gene which codes for the protein kinase involved in the DNA double-stranded break.

The DNA double-stranded break is repaired easily as the protein kinase is recruited to the site of the break where it allows the DNA repair machinery to repair the DNA.

The gene also controls the cell growth therefore this gene is important to study cancer.  Since the p53 protein is a suppressor protein which if mutated is repaired by the ATM gene and if the gene becomes mutated then the p53 repair pathway is affected.

Thus, p53 repair pathway is the correct answer.

Hostility is related to coronary heart disease and may contribute to premature death.
erik [133]

Answer:

True

Explanation:

Hostility can be explained in clear terms as a form of emotion portrayed in an aggressive manner, which is unfriendly and an arousal of anger from within as a result of denial or rejection.

Coronary heart disease occurs when major blood vessels that supply blood,oxygen,and nutrients  to the heat becomes damaged. It major cause are inflammation or cholesterol deposits in the arteries that supply all these nutrients, oxygen and  blood to the heart. This causes coronary arteries to narrow, limiting blood flow to the heart.  It is said that some slight modifications to care for coronary heart disease  include a better lifestyle changes,socialization etc, but when an individual susceptible to coronary heart diseases is hostile, it endanger the effect of such individual more to chronic effects.

Hostility levels is also related as  a better predictor of coronary heart disease risk than factors such as high cholesterol, high blood pressure etc. This is because more heart attacks are attributed to anger than high cholesterol.
