X Signed in as Lexxus Betts Hele Chapter 13 Critical Thinking Question 8 Resources previous 3 of 5 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?

The DNA polymerase is the primary enzyme involved in replication. The process of replication proceeds in various stages like initiation, elongation and termination. At each step different types of DNA binding proteins assist the DNA polymerase to continue the application process.
RNA polymersase enzyme handles the process of mRNA synthesis from DNA during trascription process. The nucleotide transferase repairs the mismatched base pairs during DNA repaire mechanism. Thus, the polymerase shows great specificity at each mechanism of DNA replication, transcription and DNA repair and recombination. At least 5 DNA polymerases are observed in E. coli. DNA polymerase I possess exonuclease activity in 3' to 5' prime direction. DNA polymerase III apart from exonuclease activity involved in replication and adds nucleotides to growing DNA strand.
