The DNA model shown (far right) is a space-filling, or CPK, model of the DNA double helix. Animated molecular models, such as the wire, or skeletal, type shown at the top of this article, allow one to visually explore the three-dimensional (3D) structure of DNA. Another type of DNA model is the space-filling, or CPK, model.
Watson and Crick completed their model, which is now accepted as the first correct model of the double helix of DNA. On 28 February 1953 Crick interrupted patrons' lunchtime at The Eagle pub in Cambridge, England to announce that he and Watson had "discovered the secret of life".

DNA, or Kidnapping, is a Danish television police procedural drama, which was broadcast from 9 September 2019. It was created by Torleif Hoppe [ da ] , [ 1 ] who is the principal scriptwriter with five episodes of season one co-written by Nanna Westh.
The two base-pair complementary chains of the DNA molecule allow replication of the genetic instructions. The "specific pairing" is a key feature of the Watson and Crick model of DNA, the pairing of nucleotide subunits. [5] In DNA, the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. The A:T and C:G pairs ...
Francis Harry Compton Crick OM FRS [3] [4] (8 June 1916 – 28 July 2004) was an English molecular biologist, biophysicist, and neuroscientist.He, James Watson, Rosalind Franklin, and Maurice Wilkins played crucial roles in deciphering the helical structure of the DNA molecule.
K80, the Kimura 1980 model, [3] often referred to as Kimura's two parameter model (or the K2P model), distinguishes between transitions (, i.e. from purine to purine, or , i.e. from pyrimidine to pyrimidine) and transversions (from purine to pyrimidine or vice versa). In Kimura's original description of the model the α and β were used to ...
These proteins are divided into histone proteins, a class of proteins that bind to DNA and give chromosomes their shape and regulate gene activity, [13] and non-histone proteins. The nucleoplasm contains many enzymes that are instrumental in the synthesis of DNA and RNA, including DNA polymerase and RNA polymerase which function in DNA ...
