Definition of DNA in English:



  • 1[mass noun] Deoxyribonucleic acid, a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.

    • ‘Almost every cell in the body of an organism has the same deoxyribonucleic acid.’
    • ‘Many molecules, especially those in living things such as sugar, fat, or protein molecules and molecules of deoxyribonucleic acid or ribonucleic acid, are much larger and more complex.’
    • ‘The development of organisms, from human bodies to viruses, depends on genetic information contained in DNA, deoxyribonucleic acid.’
    • ‘Along with several independent teams, her group is extracting DNA, or deoxyribonucleic acid, from the soil and working to clone the material.’
    • ‘Increasingly, materials scientists are taking deoxyribonucleic acid beyond its origins as a carrier of genetic code and adapting it for use as a nanotechnology tool.’
    • ‘Within the nucleus are chromosomes that contain DNA, or deoxyribonucleic acid, genetic material unique to each individual.’
    • ‘In cultured cells, the consumption of the nutrients in the medium may affect the cell metabolism by interfering with deoxyribonucleic acid, ribonucleic acid and protein synthesis.’
    • ‘DNA, or deoxyribonucleic acid, has an overall negative charge, so it might be used in a process called self-assembly to create electronic devices.’
    • ‘Each chromosome carries a single strand of deoxyribonucleic acid that threads together about 1,000 genes.’
    • ‘In general, deoxyribonucleic acid, or DNA, is a very stable molecule.’
