DNA Genetics

DNA genetics involves the study of genes, which are segments of DNA that carry instructions for building and maintaining an organism. These instructions determine inherited traits such as eye color, height, and even susceptibility to certain diseases. DNA is composed of a sequence of molecules called nucleotides, forming a double helix. The specific order of these nucleotides encodes genetic information. Genetics explores how these genes are passed from parents to offspring, how they are expressed, and how variations can lead to differences among individuals or influence health. This field helps us understand biological inheritance and can inform fields like medicine, agriculture, and forensics.
