Epigenetics and Aging | by Kendra Clark person ’ s body synthesizes proteins and thus how that body is supposed to be built and function .
Congratulations on completing the crash course in biochemistry . Now let ’ s define epigenetics .
Plain and simple , epigenetics affects how genes are read , and subsequently whether the cells should produce relevant proteins .
Genome
One ’ s genome is a person ’ s unique combination of genes or genetic makeup . Thus , the genotype is a complete set of instructions on how that
Epigenetics is the understanding that external factors affect genes . Genes are capable of being altered by external factors and influences , including diet , when and how we sleep , type and amount of exercise , level of stress , environmental exposures , and exposure to toxins-to name a few . A key component of the relevance of epigenetics to aging is that epigenetic changes are reversible and do not change your DNA sequence , but they can change how your body reads a DNA sequence .
Plain and simple , epigenetics affects how genes are read , and subsequently whether the cells should produce relevant proteins . The process is quite complex ; however , to simplify the mechanism , consider a light switch reading a gene and determining what modulation or change should occur . Like the light switch , the gene is switched on to stimulate the gene expression or off to silence the gene . Epigenetic changes occur without any alteration of the DNA sequence itself . Instead , the gene ’ s expression is changed through using different mediators .
No two individuals are alike and we all have our unique differences . The many different combinations of genes
