Jun 25, 2024 · DNA, organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.
2 days ago · Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.
Apr 8, 2019 · Deoxyribonucleic acid, or DNA, is a biological macromolecule that carries hereditary information in many organisms. DNA is necessary for the production of proteins, the regulation, metabolism, and reproduction of the cell.
Deoxyribonucleic acid ( / diːˈɒksɪˌraɪboʊnjuːˌkliːɪk, - ˌkleɪ -/ ⓘ; [1] DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
Jan 19, 2021 · 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 14, 2019 · DNA stands for deoxyribonucleic acid. It contains units of biological building blocks called nucleotides. DNA is a vitally important molecule for not only humans but also most other...
Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within...
DNA. noun. ˌdē-ˌen-ˈā. : any of various nucleic acids that are located especially in cell nuclei, are usually the chemical basis of heredity, and are composed of two nucleotide chains held together by hydrogen bonds in a pattern resembling a flexible twisted ladder compare rna.
Feb 26, 2019 · DNA, or deoxyribonucleic acid, is a molecule found inside every cell in almost every living thing. It helps cells make proteins, which they need to survive, and it facilitates reproduction.
Aug 12, 2023 · The purpose of DNA is to instruct organisms—including humans—on how to develop, survive, and reproduce. In order for this to happen, DNA sequences—known as "genes"—are converted into proteins, which are complex molecules responsible for carrying out most of the work in human bodies.
