Regulation of Processing of mRNA 4. Control of Life Span of mRNA 5. Gene Amplification 6. Post Translation Regulation and 7. Post Transcription Gene Silencing. Introduction to Gene Regulation: The [...]
Let us make an in-depth study of the regulation of gene expression in prokaryotes. All the activities of an organism are controlled by genes. Most of the genes of an organism express themselves by producing proteins. The genes which produce proteins are called structural genes or cistrons. Every cell of an organism posses all the genes. But all of them [...]
Let us make an in-depth study of the split genes or interrupted genes. After reading this article you will learn about: 1. Processing of mRNA by Splicing 2. Spliceosome 3. Mechanism of Splicing 4. Self Splicing and 5. Alternate Processing of Pre-mRNA. Processing of mRNA by Splicing: Till recently it was believed that coding sequence of DNA and amino acids [...]
