DNA contains genetic material that gets passed down to each successive generation. Learn about DNA and find out what information each strand of DNA contains.
How does DNA work? Most DNA lives in the nuclei of cells and some exist in mitochondria , which are the powerhouses of the cells. Because humans have so much DNA and the nuclei are so...
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.
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.
DNA is a long polymer made from repeating units called nucleotides. [6] [7] The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. [8] In all species it is composed of two helical chains, bound to each other by hydrogen bonds.
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. DNA is a fundamental molecule that holds life’s blueprint.
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.
The DNA that determines heritable traits is found in the nucleus of every single cell of our bodies. DNA is made up of two intertwined strands linked together by pairs of building blocks, known as bases, adenine, cytosine, guanine, and thymine.
Your DNA makes you, you -- but how does it work? These talks explore what we know about the genome, the unique genetic sequence that makes up life as we know it.
In short, DNA is a complex molecule that consists of many components, a portion of which are passed from parent organisms to their offspring during the process of reproduction.
