DNA, or deoxyribonucleic acid, is the hereditary material in humans and nearly all other organisms. It is a complex molecule that carries genetic information essential for the development, functioning, growth, and reproduction of living organisms.
Key Features of DNA:
- Structure: DNA is composed of two long strands that coil around each other to form a double helix. Each strand is made up of nucleotides, which consist of a sugar (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine).
- Function: DNA contains the instructions for building proteins, which perform most life functions. Genes, segments of DNA, dictate specific traits and functions.
- Replication: DNA can replicate itself, allowing genetic information to be passed from cell to cell and from parents to offspring.
