Rna polymerase (RNAP or RNApol) is an enzyme that is responsible for making rna from a dna template. In all cells RNAP is needed for constructing rna chains from a dna template, a process termed transcription. In scientific terms, RNAP is a nucleotidyl transferase that polymerizes ribonucleotides at the 3′ end of an rna transcript. Rna polymerase enzymes are essential and are found in all organisms, cells, and many viruses.
Genes are expressed through the process of protein synthesis. This elaborate tutorial provides an in-depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion. Also included are topics on DNA replication during interphase of the cell cycle, DNA mutation and repair mechanisms, gene pool, modification, and diseases...
Learn about the general structure of a eukaryotic gene, the transcription factors, and post-transcriptional regulation...
Part of the genetic information is devoted to the synthesis of proteins. mRNA, a type of RNA, is produced as a transcript that carries the code for protein synthesis. Read this tutorial for further details...
