Summary Introduction

Introduction: Transcription is the machinery by which RNA is synthesized where a template strand of DNA is exploited by specific polymerases enzyme (RNA polymerases) to produce RNA molecules. Synthesized RNA molecules are messenger RNA (mRNA), transfer RNA (tRNA), ribosomal RNA (rRNA), small RNAs–small nuclear RNA (snRNA), and microRNA (miRNA). Certain proteins are responsible for the production and decline of the RNA strand for transcription. Such proteins are called as transcription factors.
