Breast cancers were temporally 0 Items. EP - EPO . The RNA Polymerase III Antibody test contains 1 test with 1 biomarker. Toggle menu. The prevalence of antibodies to RNA polymerase III (anti-RNAP) differs among systemic sclerosis (SSc) cohorts worldwide. Transcription initiation requires recruitment of the complete transcription machinery to a promoter via solicitation by activators and chromatin remodeling factors. Why is RNA polymerase less accurate than DNA polymerase? It synthesises single-stranded RNA during the transcription process. Hence the error rate of the RNA polymerase is much higher than the DNA polymerase. The RNA polymerase is slow, inefficient and adds nucleotides 40 to 50 per seconds. But alike DNA polymerase, the RNA polymerase is also important for a cell. However, its contribution to cancer progression has not been extensively explored. FR - France .
