The following components of deoxyribonucleotide (DNA) have been described: 1. A Five Carbon Ring 2. Nitrogenous Base 3. A Phosphate Group. 1. A Five Carbon Ring: Deoxyribose is a pentose sugar consisting of five carbon atoms. The first and fourth carbon atoms of this sugar combine with one oxygen atom and form a ring. The fifth atom (5') forms –CH2 [...]
The below mentioned article provides a note on DNA:- 1. DNA Chemistry 2. DNA Replication 3. Carrier of Genetic Information. DNA Chemistry: DNA is found to consist of thread-like particles of high molecular weight in isolated condition. A number of units called nucleotides become linked together and form the nucleic acid. A nucleotide is composed of a molecule of Pentose [...]
In this article we will discuss about the molecular structure of nucleic acid with the help of diagrams. Nucleic acids constitute another important group of biological macromolecules present in all types of organisms where they function mainly as store-house of genetic information and as information- transfer molecules. Two types of nucleic acids: i. Ribonucleic acid (RNA) and ii. Deoxyribonucleic acid [...]
