Answer: Eating excessive quantities of such molecules could deregulate this process, increasing methylation and repressing the expression of genes that should normally be expressed.
Explanation:
DNA methylation is one of the epigenetic mechanisms involved in the regulation of gene expression, because it is a process by which methyl groups are added to DNA.
Methylation then modifies the function of DNA when it is found in the promoter gene, it is essential for normal development and is associated with a number of key processes, including genomic imprinting, inactivation of the X chromosome, repression of repeating elements, aging, and carcinogenesis. Usually, <u>it acts to suppress gene transcription.</u>
For example, folic acid is essential for the rapid cell division that occurs during early fetal development and it also plays an important role in methylation and thus in gene regulation. <u>The metabolism of these vitamins is aimed at achieving adequate levels of DNA methylation, necessary for the cellular processes</u>. Eating excessive quantities of such molecules could deregulate this process, <u>increasing methylation and repressing the expression of genes that should normally be expressed</u>.
You can use a punnet square to find this out:

<span>A monomer is a molecule that bonds with other identical molecules to form polymers. In this case, the correct answer is glucose, but galactose and fructose also belong in the monomer group, just aren't mentioned in the question. Sucrose is a somewhat archaic term for sugars in general, any simple sugar like the one we eat on a regular basis. </span>
The human ABI Blood group is a part of codominance.
Answer:
The lub sound represents the <u>closing </u> of the atrioventricular valves and the dub sound represents the closure of the valves <u>between the ventricles and arteries.</u> Doctors can also use stethoscopes to monitor respiratory function. A wheezing or whistling sound most likely indicates<u> a constricted trachea.</u>
Explanation:
One can easily feel the heartbeat sound in the form of lub-dub by the stethoscope. The lub sound depicts the closure of the tricuspid valve and the mitral valves. Dub depicts the closure of the aortic and pulmonary valves.
A wheezing sound can be felt in the respiratory tract when an inflammation or blockage occurs in the airways or trachea. The wheezing sound is generally heard at the time of exhaling.
