In a peptide bond formation between two amino acids, a water molecule (A) is liberated. This reaction is called condensation. The water molecule is formed by a single hydroxide ion being removed from one amino acid, and a single hydrogen ion from the second amino acid, which combine to form a water molecule.
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.

Total 46, 23 from each parent
Explanation:
Answer: Masseter and temporalis
Explanation:
Bruxism is a condition in which the person grind or clash teeth. A person may unconsciously clench teeth when he is awake or even when they are sleeping.
It is a kind of sleep related disorder which is also associated with snoring, pause in breathing.
It can be frequent and sever and the muscles responsible for sleeping bruxism is masseter and temporalis.
The answer is transport vesicles
