1. Epigenetics

   In biology, and specifically genetics, epigenetics is the study of changes in gene expression or cellular phenotype, caused by mechanisms other than changes in the underlying DNA sequence – hence the name epi- -genetics, some of which have been argued to be heritable. It refers to functionally relevant modifications to the genome that do not involve a change in the nucleotide sequence. Examples of such modifications are DNA methylation and histone modification, both of which serve to regulate gene expression without altering the underlying DNA sequence. Gene expression can be controlled through the action of repressor proteins that attach to silencer regions of the DNA. These changes may remain through cell divisions for the remainder of the cell's life and may also last for multiple generations. However, there is no change in the underlying DNA sequence of the organism; instead, non-genetic factors cause the organism's genes to behave differently. There are objections to the use of the term epigenetic to describe chemical modification of histone, since it remains unclear whether or not histone modifications are heritable.

Examples of epigenetics in a Sentence

1. Joanna Kitlinska:

   This new field of inherited paternal epigenetics needs to be organized into clinically applicable recommendations and lifestyle alternations, and to really understand the epigenetic influences of a child, we need to study the interplay between maternal and paternal effects, as opposed to considering each in isolation.

2. Xiaobin Wang:

   Our finding is that epigenetics appear to be a mechanism to regulate whether someone can develop the food allergy, gene codes are relatively stable, but the epigenetic part is dynamic.
