Definition of dna. DNA and ribonucleic acid (RNA) are nucleic acids.



Definition of dna. Jan 19, 2021 · DNA is the hereditary material in humans and almost all other organisms. Base pairs are the compounds adenine (A), cytosine (C), guanine (G) and thymine (T). Alongside proteins, lipids and complex carbohydrates Definition of DNA Your genome is the complete set of instructions your body needs to function. It codes genetic information for the transmission of inherited traits. It’s made of a long molecule called deoxyribonucleic acid, or DNA for short. It is a double helix of four chemical bases that store and transmit genetic information. Aug 24, 2020 · Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids. Sep 13, 2023 · DNA stands for Deoxyribonucleic acid, a macromolecule that carries genetic information in all living organisms, from the tiniest microorganisms to the most complex multicellular humans. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities. DNA is a fundamental molecule that holds life’s blueprint. These are called adenine, cytosine, guanine and thymine – usually shortened to A, C, G and T. Deoxyribonucleic acid (pronunciation ⓘ[1]; DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. Two strands of DNA together form a double helix — a bit like a spiral staircase. Sep 20, 2025 · DNA is an organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. . DNA definition: deoxyribonucleic acid: an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms, constructed of two nucleotide strands coiled around each other in a ladderlike arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine Mar 17, 2023 · What is DNA? Deoxyribonucleic acid, or DNA, is a molecule that contains the instructions an organism needs to develop, live and reproduce. 4 days ago · Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. Sugars and phosphates make up the sides and base pairs make up the middle. The meaning of DNA is any of various nucleic acids that are usually the molecular basis of heredity, are constructed of a double helix held together by hydrogen bonds between purine and pyrimidine bases which project inward from two chains containing alternate links of deoxyribose and phosphate, and that in eukaryotes are localized chiefly in cell nuclei. The bases can be arranged in lots of different orders, known as the DNA Jul 9, 2025 · DNA (deoxyribonucleic acid) is a set of instructions for creating the proteins that make your body work. DNA is the molecule inside cells that contains the genetic information responsible for the development and function of an organism. It guides cell growth, function, and replication. Jul 30, 2025 · DNA is material found in all living things that acts as a carrier for genetic information. It is made up of a double-stranded helix of nucleotides that form base pairs: adenine (A) with thymine (T), and guanine (G) with cytosine (C). DNA is made up of four building blocks, or bases. Introduction: What Is DNA? Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. ototff3 qcfn9p f5g k2svd jau cuegv lbm evxtj5 3e ubj2osa
