Just so, what is the structure of DNA and who discovered it?
Watson and Crick discover chemical structure of DNA. On this day in 1953, Cambridge University scientists James D. Watson and Francis H.C. Crick announce that they have determined the double-helix structure of DNA, the molecule containing human genes.
Similarly, how is the structure of DNA related to its function? DNA winds into a double helix, with hydrogen bonding between the bases of each strand like the rungs of a ladder. This structure enables DNA to coil so that the long molecule is compact and lots of information can be stored in a small space.
In this way, how did Watson and Crick describe the structure of DNA?
Watson and Crick showed that each strand of the DNA molecule was a template for the other. During cell division the two strands separate and on each strand a new "other half" is built, just like the one before. By 1962, when Watson, Crick, and Wilkins won the Nobel Prize for physiology/medicine, Franklin had died.
What is DNA made up of?
DNA structure DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
