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 …

Jan 23, 2026 · 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 · DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone. DNA is the hereditary material in humans and almost all other organisms. Genes are made up of DNA.

Jul 10, 2025 · DNA, or deoxyribonucleic acid, is the genetic material found in all living organisms. It is made of long chains of chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

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.

The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to …

Apr 5, 2025 · DNA is the molecule that carries hereditary information from one generation to the next. This means that offspring inherit a combination of genes from their parents, and this genetic …

1.2 DNA Overview Deoxyribonucleic acid (DNA) is the hereditary material common to all living things. DNA is a macromolecule made up of a string of smaller units called nucleotides. Each nucleotide is …
