We also customise the content as per your requirement for companies platform providers colleges etc . 7 Active driving force "The Joy of Happy Learning" -- is what makes difference from other digital content providers. We consider Student needs, Lecturer needs and College needs in designing the 3D & 2D Animated Video Lectures. We are carrying a huge 3D Digital Library ready to use. Structure of DNA: The DNA molecule is a polymer consisting of several thousand pairs of nucleotide monomers.Each nucleotide consists of three components. They are 1. Pentose sugar deoxyribose 2. Phosphate group 3. Nitrogenous base Nucleoside = deoxyribose + nitrogenous base Nucleotide = deoxyribose + nitrogenous base + phosphate Pentose sugar:deoxyribose sugar is a pentose sugar with five carbon atoms. Phosphate: the phosphate is attached to the adjacent pentose sugar alternately at their 5th and 3rd carbon atoms by phospho -- diester bonds. The phosphate and pentose sugar constitute the back bone of nucleic acids. Nitrogen bases: there are two types of nitrogen bases 1.Purines adenine and guanine and 2.Pyramidines cytosine and thymine Nitrogenous base is linked to the pentose sugar through N- glycosidic linkage to form a nucleoside. When a phosphate is linked to 51 OH of a nucleoside through phosphoester linkage a corresponding nucleotide is formed. Two nucleotides are linked through 31 -- 51 phosphodiester linkage to form dinucleotide. More nucleotides are joined to form a polynucleotide chain. A polymer has at one end a free phosphate moiety at 51 end of ribose sugar, at the other end the ribose sugar has 31 OH group. The back bone in a polynucleotide chain formed due to sugar and phosphates. The nitrogenous bases linked to sugar moiety form the back bone. |
