Virology Live # 7: Transcription and RNA processing

When DNA viral genomes get in the cell, mRNAs should be made prior to DNA duplication can happen. This action, called transcription, can just take place on double-stranded design templates. The enzyme that performs transcription, DNA reliant RNA polymerase, might be encoded by the cell or by the viral genome. In this session we go over guideline of transcription, favorable feedback loops and transcriptional waterfalls and how these coordinate the synthesis of viral DNA and structural proteins. We likewise think about RNA processing, the addition of a 5′- cap, poly( A) tail, and splicing, the myriad of noncoding RNAs and RNA methylation that can manage gene expresssion.
