In this article we will discuss about Gene:- 1. Introduction to Gene 2. The Changing Concept of Gene 3. Fine Structure. Introduction to Gene: Mendel's, (1865) experiments with Garden pea plant showed that certain hereditary "factors" were concerned in determining the appearance of certain morphological traits. Such Mendelian "factors" were described as "gene" by Johanssen (1909) and these genes were [...]
In this article we will discuss about Gene Control and Transcriptional Control:- 1. Transcriptional Control in Yeast 2. Mechanism of Action of Activator and Repressor in Eukaryotes 3. Regulation of Gene Expression with Repressors 4. Some Examples of Gene Regulation in Eukaryotes 5. Translational Control at the Initiation Level 6. Gene Regulation at the Level of RNA Processing and Others. [...]
The below mentioned article provides an overview on Expression Hosts and Vectors in Eukaryotes. One of the main objectives of gene cloning is to note the expression of the cloned gene encoding the protein. It is generally done in a foreign organism, for producing at a high level and again some hosts are needed for this purpose. These vectors are [...]
