This article throws light upon the following three main types of gene action. The types are: 1. Additive Gene Action 2. Dominance Gene Action 3. Epistasis. Type # 1. Additive Gene Action: When the genes act in such a way that substitution of one allele for another produces same plus or minus effect regardless of other gene (s) and the [...]
In this article we will discuss about the Mechanism of Protein Synthesis in Prokaryotes and Eukaryotes. Protein synthesis in the cell is conducted by ribosomes that are found attached to the membrane of endoplasmic reticulum and microsomes, as well as in free state in the groundplasm. The main components that take part in protein synthesis at cellular level are: 20 [...]
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. [...]
