The following points highlight the top three types of multi-gene families. The types are: 1. Pseudo Genes 2. Selfish Genes 3. Split Gene - Exons and Introns. Multi-Gene Families: Type # 1. Pseudo Genes: Genes often exist which resemble other genes but their base sequence shows errors that make it impossible to contain biological information. These are pseudo genes which [...]
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 below mentioned article provides a short note on the Essential Properties of Gene. There are, however, certain essential properties of genes. As the genes control all characters transmitted from generation to generation, the gene must have the stability or permanency in the cell, principally in the nucleus. It implies that, it must be an essential component of all cells [...]
