Messenger RNA is the link between the genome and the cell cytoplasm. For this reason alone it is of central importance in the study of gene action. This study has been greatly facilitated by the methods which are now available for the isolation and purification of mRNA's (and other RNA's as well). Purified mRNA is, of course, a prerequisite for [...]

In this article we will discuss about:- 1. Introduction to the Kinds of Genes in Eukaryotes 2. Repetitive DNA Sequences 3. Transcription of DNA and RNA in Eukaryotes 4. Mitochondrial DNA and RNA. Introduction to the Kinds of Genes in Eukaryotes: The principle of "one gene, one protein" does not apply to all genes. There are genes which do not [...]
