The below mentioned article provides a short note on the Homeotic Genes. Homeotic genes constitute an intricate regulatory network, in which one gene may activate or repress other genes Homeotic genes are involved in regulation of development through a predetermined pathway in which specific genes are turned on and off at particular times. Homeotic genes act in a transcriptional cascade, [...]
The following points highlight the three main stages for mechanism of induced mutagenesis. The stages are: 1. Base Analogue Incorporation 2. Base Alteration 3. Distortion of DNA. Stage # 1. Base Analogue Incorporation: Some chemical compounds are sufficiently similar to the nitrogen bases of DNA so that they occasionally are incorporated into DNA in place of normal bases, such compounds [...]
Learn about the relationship between Gene and Enzyme. An understanding of the relationship of the gene and the enzyme is crucial for an analysis of the basis of growth and development of an organism. It has been established through varied lines of evidences that genes control all hereditary characters of an organism, which are transmitted from generation to generation. Simultaneously, [...]
