how is rna polymerase different from dna polymerase
7.Subunits contained in RNA polymerases must unwind the templates of DNA and the DNA polymerases do actually abide the helicase that the double helix may be open just in front of it. 8.Lastly, DNA polymerase is a lot faster compared to RNA polymerase..DNA is double stranded whereas RNA is a single stranded. 5.DNA contains the pentose sugar deoxyribose while RNA contains the pentose sugar ribose. 6.DNA polymerase will be continuous till the work is finally done wherein RNA polymerases will continue but eventually may break in the event it will reach a âstopâ cycle.
