Describe epigenetics.
Your surroundings and behaviours, like the foods you consume along with how engaged you are, are just as crucial to your health as your genes. Epigenetics analyses how environmental factors and behaviour can alter how your genes function. While epigenetic alterations are recoverable and do not alter the structure of your DNA as genetic mutations do, they can vary how your body interprets a DNA sequence. The frequency or timing of protein synthesis from your genes’ directions is called gene expression. While variations in genes can impact which proteins are produced, epigenetic variations impact gene expression, turning genes “on” and “off.” It is simple to observe how your genes, behaviours, and surroundings are related because your environment and behaviours, such as diet and physical activity, can cause epigenetic alterations.

What Is the Process of Epigenetics?
Various epigenetic modifications influence gene expression. Various epigenetic modifications include:
Methylation of DNA
When DNA is methylated, a chemical group is added. This category is usually introduced to particular regions of DNA, where it prevents proteins from attaching to DNA to “read” genes. Demethylation, a procedure, can be used to get rid of this chemical group. Genes are usually switched off by methylation and switched on by demethylation.
Histone alteration
Histone proteins are encircled by DNA. Histones that bind closely together prevent proteins that ‘read’ the gene from simply accessing the DNA, turning the gene “off.” Histones that are not tightly packed allow proteins that ‘ read’ genes to access more DNA that is accessible or not curled around a histone, turning the gene “on.” Histones can have chemical groups added or subtracted to make them firmly or loosely assembled, which turns genes “on” or “off.”
RNA with no codons.
Coding and non-coding RNA are produced using directions found in your DNA. Proteins are created using coding RNA. By joining with specific proteins and coding RNA to cut down the coded RNA, which prevents it from being utilised to produce proteins, non-coding RNA regulates gene activity. Additionally, proteins may be enlisted by non-coding RNA to change histones and switch genes “on” or “off.”
How Is Epigenetic Modification Possible?
As you become older, both because of biological processes and ageing and in reaction to your behaviours and surroundings, your epigenetics alter.
Growth and Epigenetics
Epigenetic alterations start to take place before birth. Despite sharing the same genes, your cells all appear and behave differently. Epigenetics acts as the key factor in deciding which function a cell, such as a heart cell, neuron cell, or skin cell, will have as you grow and develop.
Age, Epigenetics
Your epigenetic makeup evolves. Your epigenetic makeup at birth is different from what it is when you are a child or an adult.
Versatility and Epigenetics
Not all epigenetic modifications are long-lasting. In reaction to adjustments in behaviour or environment, some epigenetic modifications can be introduced or eliminated.
