DNA - structure In DNA, these bases are cytosine (C), thymine (T), adenine (A) and guanine (G). Note: These are called "bases" because that is exactly what they are in chemical terms. They have lone pairs on nitrogens and so can act as electron pair donors (or accept hydrogen ions, if you prefer the simpler definition).

What Is DNA?- Meaning, DNA Types, Structure and Functions The DNA molecule consists of 4 nitrogen bases, namely adenine (A), thymine (T), cytosine (C) and Guanine (G), which ultimately form the structure of a nucleotide. The A and G are purines, and the C and T are pyrimidines. The two strands of DNA run in opposite directions.

The Structure Of DNA and RNA : Plantlet A DNA molecule consists of two polynucleotide chains, linked by hydrogen bonds between bases. In DNA there are four bases - adenine always pairs with thymine, and cytosine always pairs with guanine. RNA, which comes in several diff erent forms, has only one polynucleotide chain, although this may be twisted back on itself, as in tRNA.

DNA: Structure, Forms and Functions (With Diagram) DNA contains β D 2′-deoxyribose sugar. It is a five-carbon sugar; hence it is a pentose sugar. Since one oxygen atom at the 2′ carbon is missing it get its name 2′-deoxy. The 2′- deoxy-containing backbone is more resistant to hydrolysis than the riboform. D-ribose does not mean dextrorotary ribose.

Structure of DNA: Primary and secondary structure The primary structure of DNA is simply the sequence of nucleotides. The sugar-phosphate chain is called the DNA backbone, and it is constant throughout the entire DNA molecule. The variable portion of DNA is the sequence of nitrogenous bases.

The DNA Structure Model - A History of the Double Helix The discovery of the double helix structure of DNA is most often attributed to James Watson and Francis Crick. Using Chargaff's rules and the works of English scientists Rosaline Franklin and Maurice Wilkins, they built a 3D model of the double-helical structure of DNA. American geneticist Maclyn McCarty with Francis Crick and James D. Watson.
