Let's suppose you were interested in developing drugs to prevent epigenetic changes that may contribute to cancer. What cellular
Vaselesa [24]

Answer:

Potential targets:

1- DNA methyltransferases

2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.

3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.

Explanation:

Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

Understanding what you do about the structure of DNA so far, do you think that every organism's DNA will look and act the same?
Over [174]
Every organism’s DNA will not look and act the exact same way. If the parent reproduces asexually is the only exception to that rule. However, if all organism’s DNA resembled and acted as a deer’s DNA, then all organisms would be deer. Therefore, there are genetic differences that separate species and ensure different behaviors from organism to organism. While the DNA will be similar by using the same four nucleic bases, there is an entirely different combination of those bases from organism to organism.
