In this article we will discuss about the chemical nature of the genetic material of organisms. The knowledge about the chemical nature of the genetic material was gathered from a number of experimental observations made with bacteria and viruses. These experimental observations led to the conclusion that all cellular organisms have DNA (deoxyribonucleic acid) as the genetic material. Only some [...]
In this article we will discuss about:- 1. Meaning of the Genetic Code 2. Properties of the Genetic Code 3. Nature 4. Universality 5. Deciphering the Genetic Code. Meaning of the Genetic Code: Although the concept of a gene as a unit of heredity is about a century old (the term coined in 1909) its role in the life of [...]
The following points highlight the six main stages involved in protein synthesis of prokaryotic and eukaryotic systems. The stages are: 1. Amino Acid Activation and Formation of Amino Acyl-t-RNA 2. Binding of m-RNA to the Ribosome 3. Formation of Initiation Complex 4. Polypeptide Chain Elongation 5. Polysomes 6. Co Transcriptional Translation. Stage # 1. Amino Acid Activation and Formation of [...]
