👉 Epigenetics is a branch of biology that examines how genetic material can be passed down to offspring and how this inheritance can lead to changes in gene expression without altering the DNA sequence. This process, also called somatic cell nuclear recombination (SCNR), involves modifications to genes due to environmental factors such as exposure to certain chemicals or radiation. Epigenetic modifications include changes in the expression of genes that do not change the DNA sequence itself but can influence how those genes are regulated by other molecules.
