What is human genetics?<\/strong><\/h2>\n

Human genetics is the science that studies heredity and variability in the human body. It examines how traits are passed from parents to children, which genes determine appearance, susceptibility to disease, metabolic features, and even behavioral characteristics.<\/p>\n

Thanks to advances in this field, it has become possible not only to understand the mechanisms of heredity, but also to develop methods for the prevention of genetic diseases, personalized medicine, and even DNA editing.<\/p>\n

The structure of DNA and the role of genes<\/strong><\/h2>\n

The basis of heredity is deoxyribonucleic acid (DNA)<\/strong>, which is found in every cell in the body. It consists of two helical chains that form a double helix and contains four basic components: adenine (A), thymine (T), guanine (G), and cytosine (C).<\/p>\n

Genes are sections of DNA that encode information about the structure of proteins and perform regulatory functions. Each person has approximately 20,000\u201325,000 genes<\/strong>, which are responsible for all biological processes in the body.<\/p>\n
