DNA is a polymer of nucleotides that forms a double helix and carries genetic information for all living organisms and many viruses. Learn about the chemical structure, base pairing, replication, transcription and translation of DNA, as well as its evolution and uses in technology.
9 sty 2021 · Learn about the structure of DNA, the double helix, the nucleotides, the base pairs, and the discovery of DNA by Watson, Crick, and Franklin. Compare DNA with RNA and understand DNA replication.
Kwas deoksyrybonukleinowy, DNA (z ang. deoxyribonucleic acid), daw.kwas dezoksyrybonukleinowy – wielkocząsteczkowy organiczny związek chemiczny z grupy kwasów nukleinowych. U eukariontów zlokalizowany jest przede wszystkim w jądrach komórek, u prokariontów – bezpośrednio w cytoplazmie, natomiast u wirusów – w kapsydach.
6 dni temu · Learn about DNA, the organic chemical that codes genetic information for all living organisms. Discover its structure, function, discovery, and role in inheritance, replication, and transcription.
13 wrz 2023 · Learn about the definition, discovery, structure, and functions of DNA, the molecule that carries genetic information in all living organisms. See how DNA is composed of nucleotides, base pairs, and grooves, and how it regulates protein synthesis, replication, and evolution.
A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together (Figure 4-3).
17 mar 2022 · Learn how Watson and Crick determined the double helix structure of DNA using X-ray crystallography and Chargaff's rules. Compare the building blocks and base-pairing of DNA and RNA nucleotides.
