An introduction to epigenetics
Cancer can occur when certain normal genes are switched on or off as a result of environmental epigenetics — influences that occur throughout your life some drugs have already been developed to correct the on/off switch for some types of cancer. In spite of the fact that most high school and college students study biology and with it the genetic component of our human development, yet without the introduction to epigenetics it appears that the study of epigenetics is limited to advance studies and mostly in elite universities.

Epigenetics is a function of chromosome structure for transcription to actually take place, all the transcription factors and enzymes that are required for gene expression must be able to access the dna that contains the genes that are to be expressed, but chromosome structure will determine if this can be done or not, and can therefore .

In this review, we introduce the reader to epigenetic mechanisms and describe a potential role for dynamic epigenetic changes in mediating addictive behaviours via long-lasting changes in gene expression. The importance of epigenetics is underscored by many diseases that can develop due to mutations in epigenetic regulatory proteins, misregulation of the epigenetic machinery, and aberrant placement or removal of epigenetic marks the reversible nature of epigenetic alterations is an attractive target for therapeutics that can help reset the . Introduction of the role of epigenetics in obesity and its metabolic complications no evidence yet exists that the rapid worsening of the obesity epidemic is due to the entry of a new, isolated, widespread genetic abnormality that has arisen and increased in prevalence in just the past few decades.

Genetics and epigenetics go hand-in-hand, so this introductory booklet covers both much of human genetic variation is a consequence, through natural selection, of life- challenging encounters during our evolutionary history.
Addiction is a debilitating psychiatric disorder, with a complex aetiology involving the interaction of inherited predispositions and environmental factors emerging evidence suggests that epigenetic alterations to the genome, including dna methylation and histone modifications, are important mechanisms underlying addiction and the .
