Sentences with phrase «epigenetic effects»
"Epigenetic effects" refer to changes in gene activity and gene expression that occur without altering the underlying DNA sequence. These changes can be influenced by various factors such as the environment, lifestyle, and experiences. Epigenetic effects can potentially impact the functioning and behavior of cells, leading to long-term effects on an individual's health and development. Full definition
