In this article we will discuss about the One Gene-One Polypeptide Concept. It is a fact that hereditary characters are maintained and transmitted from one generation to another through DNA molecules, because DNA can duplicate itself and duplicated molecules can be passed on to the offsprings. The general activity of genes brings about expression of hereditary traits in the organism. [...]
The below mentioned article provides a study note on the Operon Concept. The DNA present in a cell contains genetic information for all the proteins required by an organism and may contain from few to thousands of genes. All the functional genes do not make polypeptides all the times. Though the different types of cells in the body of an [...]
The below mentioned article provides an overview on the Genetic Code. From the study of protein synthesis, it is evident that amino acid sequence in the protein molecule is determined by DNA which carries information for this purpose. But where does the information lie? If we look at DNA chain the deoxy-ribonucleotides backbone seems to be of no help as [...]
