  3. Introduction • In the year 1950 – 1951 (M.H.F Wilkins) and Rosalind Franklin , the english physicians studied the structure of DNA of many living things by using the technique of (X – ray diffraction). The structure of DNA of many living things is very similar to each other and composed of one or more types of Nucleiolite which looks like a shape of spiral.

  4. DNA structure The figure on the righthand side represents a DNA structure. Chemically, DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. Each type of base on one strand forms a bond with just one type of base on the other strand. This is called complementary base pairing.

  5. Properties of DNA DNA is a long polymer made from repeating units called nucleotides. The DNA chain is 22 to 26  Ångströms wide (2.2 to 2.6 nanometers), and one nucleotide unit is 3.3 Å (0.33 nm) long. Although each individual repeating unit is very small, DNA polymers can be very large molecules containing millions of nucleotides. For instance, the largest human chromosome, chromosome number 1, is approximately 220 million base pairs long. The backbone of the DNA strand is made from alternating phosphate and sugar residues. The sugars are joined together by phosphate groups that form phosphodiesterbonds.

  6. Image of Property of DNA The DNA double helix is stabilized by hydrogen bonds between the bases attached to the two strands. The four bases found in DNA are adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T). These four bases are attached to the sugar/phosphate to form the complete nucleotide, as shown for adenosine monophosphate.
