Suppose these two chromosomes are found in a cell nucleus during prophase. what is the relationship between chromatids a, b, c,

Musya8 [376]

In this image we can see that A is identical to B, and C is identical to D.

Chromatid (Cht) is a DNA molecule (the nucleofilament) associated with histone proteins (PH) and non-histone proteins (PNH)
<span>Each chromosome of a cell may consist of one or two chromatids depending on its state: just after a mitosis, or after the second meiotic division, each chromosome consists of only one chromatid, the rest of the time, after DNA replication, each chromosome consists of two completely identical chromatids, connected by the centromere, thus giving the two rods the shape of an X.</span>

What are known causes of epigenetic effects, and how do they

OverLord2011 [107]

Answer:

Epigenetic effects can be caused by DNA heterochromatin and/or histone silence or activate.

As such, they can different chromosomes or certain chromosomal regions and be responsible for parental imprinting or influencing gene activity in oxidation and reduction.

Patterns of nucleotide demethylation and hypermethylation are often activate when cancer cells are compared to normal cells.

Explanation:

Cells acquire various patterns of gene expression during differentiation to adapt to a changing environment. Epigenetic and genetic alterations are considered as two independent mechanisms that participate in the onset and progression of cancer. Epigenetic mechanisms can be as important for biological events as genetic mechanisms, which do not imply a change in the DNA sequence, but do have an important role in the modification of gene expression.
