In this article, we will discuss about the regulation of gene expression in prokaryotes. The Operon Model: Francois Jacob and Jacques Monod (1961), two French geneticists, discovered while studying bacteria, that the enzymes synthesized by them can be placed in two categories: (i) Those that are synthesized all the time and occur in relatively constant concentrations, such as enzymes of [...]
Let us discuss about the mechanism of gene expression and central dogma of molecular biology. Mechanism of Gene Expression: A gene contains the blue print or code for a particular polypeptide in the form of a specific sequence of its base pairs. It transfers its code to mRNA transcribed from it. The process is called transcription. Other genes transcribe rRNA [...]
This article throws light upon the top three things to know about gene expression. The top three things about gene expression are: (1) RNA Polymerase of Prokaryotes (2) Process of Transcription in Prokaryotes and (3) Process of Transcription in Eukaryotes. Introduction: Transcription is the process by which genetic information from DNA is transferred into RNA. DNA sequence is enzymatically copied [...]
