Functions of Taq DNA Polymerase in PCR Reaction

Every gene in organisms contains regulatory regions stretching from 100 to 1000 base pairs called upstream of transcriptional start site which located within regulatory regions which called transcription factors banding sites or motif therefore transcription factors or motifs influence gene expression by binding to specific location in the respective gene regulatory regions. Hence transcription factor binding sites can be located anywhere within regulatory region and may vary slightly across different regulatory regions because non essential bases could mutate because RNA polymerases used for initiation complex of transcription binding sites: (RNA Poly-1 specific for Ribosomal RNA) (RNA Poly-2 specific for all protein genes) (RNA poly Poly-3 specific for Transfer and Ribosomal RNA) (Watch Related Video in #geneticteacher) #geneticteacher
