Animation of a DNA strand showing genes being activated (highlights). Genes are discrete sections of DNA that can be expressed to produce proteins. The sequence of bases along the DNA strand determines the protein produced. Genes can be switched on and off by a variety of factors, including environmental factors, that elicit a heritable chemical change to the DNA molecule. The study of the heritability of gene expression, as distinct from DNA sequence, is known as epigenetics. | |
