- During the process of transcription, the polymerase must handle several distinct polynucleotide chains: the double-stranded DNA ahead of the polymerase, the single-stranded template DNA, the nontemplate DNA strand, and the freshly-synthesized mRNA. How does the polymerase keep each of these strands--as well as the incoming ribonucleotides needed for the polymerase reaction--separate?arrow_forwardThe double-stranded DNA sequence for a bacteria is shown below and it's coding for a hypothetical protein. The strand on top reads 5' to 3* left to right, while the strand on the bottom reads 5' to 3' right to left. The nucleotides are numbered 1 to 100. REMINDER: For this problem, transcription begins with and includes the red and underlined C/G (top strand/bottom strand) base pair and RNA polymerase proceeds from left to right along the DNA. 1 20 40 5'-GTGTCCGTCTAATATTGTGAGATGTTATATCCCGCCGTCAACACCATCAA-3' ------+ 3'-САСAGGCAGATTATAACAСТСТАСААТАТAGGGCGGCAGTTСTGGTAGTT-5* 60 80 100 5'-ACAGGATAATCGCCTGCTGGGGCAAAGGCGGTGAAGGTAAAGGTGTTGCC-3' -------+ 3'-TGTCCTATTAGCGGACGACCCCGTTTCCGCCACTTCCATTTCCACAACGG-5' 1.
