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.
Answer:
A sequence of three nitrogenous bases in a messenger-rna molecule is known as <em><u>Codon</u></em>
Explanation:
Codon is a triplet of three nitrogenous bases present in mRNA. It can be any three from uracil, adenine, guanine or cytosine. They are arranged in specific order and code for specific amino acids.
Occurs in the mitachondria - D
uses energy in sunlight - E
does not involve oxygen- A
Plants and algae- C
Works together to perform a function ( B)
Last two I’m not too sure though
Basically all of the choices given are failure of negative feedback mechanisms to maintain homeostasis. The correct option among all the options that are given in the question is the last option or option "E". I hope that this is the answer you were looking for and it has come to your help.
