Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as transfer RNA  or small nuclear RNA genes, the product is a functional RNA.Most mechanisms that control gene expression do so by controlling transcription, the synthesis of RNA. However there are other mechanisms for controlling the rate of protein synthesis that occur downstream between transcription and translation.In order to get more information about such important topic in form of  Gene Expression and Regulation Test Online question answer mcqs quiz then just follow the link given below accordingly.
