DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential …

Dec 11, 2025 · DNA is an organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits.

Jul 9, 2025 · DNA (deoxyribonucleic acid) is a set of instructions for creating the proteins that make your body work. Two strands of DNA together form a double helix — a bit like a spiral staircase.

Aug 24, 2020 · Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique.

Jan 19, 2021 · What is DNA? DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA.

Aug 26, 2025 · DNA is a molecule found in most cells that holds each person’s unique genetic code. It is responsible for coding proteins, which are essential to cell growth and development.

Jul 27, 2025 · Inside every cell in your body—skin cells, brain cells, even the ones in your eyelashes—is a copy of this script. This molecule, deoxyribonucleic acid or DNA, is the instruction manual that not …

The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to …

A mutation is a change in DNA, the hereditary material of life. An organism’s DNA affects how it looks, how it behaves, and its physiology. So a change in an organism’s DNA can cause changes in all …

Today, the DNA double helix is probably the most iconic of all biological molecules. It's inspired staircases, decorations, pedestrian bridges (like the one in Singapore, shown below), and more. I …
