you are doing a biochemical analysis of molecules from cells from patients with a certain disease compared to cells from control patients who do not have the disease. you find that patients with the disease have unusually high levels of cytosine molecules with ch3 groups attached to their cells. which modification has taken place in the cells from the disease patients?

The "epigenetic modification," also known as "DNA methylated bases," refers to the cell change associated with variable levels of cytosine methylation on the cytosine bases of illness patients.

What is Epigenetics?

The study of epigenetics, a subfield of genetics, aims to understand how various chemical modifications to the DNA nucleotide sequence and related chromatin proteins (histones) may modify the expression of some genes. Understanding both healthy development and disease states depends on this information.

Histone acetylation and/or methylation, DNA methylation localized on CpG islets (cytosine-rich regions), non-coding RNA pathways, and other epigenetic modifications are examples of changes that regulate how genes are produced in specialized eukaryotic cells.

This information leads us to the conclusion that the field of genetics known as epigenetics studies how chemical groups added to DNA change its phenotypic.
