These modifications are known as epigenetic changes.

Some environmental factors, such as tobacco, or nutrition can initiate chemical processes that lead to changes in the epigenome. Environmental factors can modify the epigenetic state and influence gene activity.

Thus, for example, mechanisms such as memory and learning, cognitive deterioration associated with old age or behavioral disorders, are largely epigenetically regulated.]]> 2023-02-20 21:14:35 UTC https://padlet.com/anasofiareyesmarin14/p5dxewq89utc8mjp/wish/2488884336 When did epigenetics emerge? anasofiareyesmarin14 https://padlet.com/anasofiareyesmarin14/p5dxewq89utc8mjp/wish/2488886633 The term epigenetics was coined by Waddington in 19391, who defined it as "the study of all the events that lead to the unfolding of the developmental genetic program" or the complex "developmental process that mediates between developmental genotype and developmental phenotype."]]> 2023-02-20 21:19:09 UTC https://padlet.com/anasofiareyesmarin14/p5dxewq89utc8mjp/wish/2488886633
