Introduction - The important characteristic of the gene is to store and express the genetic information that will contribute towards the phenotype, and will be passed on to successive generation. The idea that genes control the metabolism was put forward as early as 19..

In higher eukaryotes the genome is highly complex. Drosophila for example, has any where between 5,000 and 10,000 genes. Human haploid genome is known to have any where between 30,000 and 1,00,000 genes. As a result gene expression in eukaryotes is high..

Summary - The molecular mechanism by which a gene shows to potential in the phenotype of an organism, is called gene expression. Every gene contains the blue print required for the function of a given polypeptide, in the form of a specific sequence of nucleotides...

This gene controls a specific series of structural genes, and lies adjacent to them. It remains turned on because it is not bound by the repressor protein produced by the regulator gene. Therefore, the cistrons keep functioning, producing enzymes. The latter catalyse t..

All the genes do not play the same role, nor are all the genes active all the time. With regard to their role and activity, the genes are of two different types- Those genes are constantly transcribed and expressed in the cells because the products ..

Gene Regulation in Eukaryotes - In eukaryotes, the genes that code for the enzymes needed to catalyse the various steps of a particular metabolic pathway may not be adjacent or even be in different chromosomes. However, these genes are regulated by operon model as in b..

Gene Metabolism Relationship - The concept that genes have the information to produce enzymes which are proteinaceous in nature was proved by George Beade and Edward Talium in the early 1940s with their work on the fungus Neurospora crassa. This mould can normally grow in a simp..

Concentration dependence of rate is a differential equation (equation 8). It is tedious to determine the instantaneous rates from the slopes of the tangents for each value of t and this in turn makes the rate law determination difficult. To avoid this difficulty, the i..
