How are dna and rna polymerases different
Obviously, the first difference is the molecules they synthesize. “The DNA polymerase synthesizes DNA strand while the RNA polymerase synthesizes the RNA strand” DNA synthesis occurs during replication, thus the DNA polymerase functions during the replication, always. While the RNA polymerase … Ver mais DNA polymerase is an enzyme that synthesizes DNA in all living organisms and is thus present in almost all organisms on earth. It helps in replication to copy DNA using the single-stranded primer- either DNA or RNA. … Ver mais As like the DNA polymerase, the RNA polymerase is also present in all living organism, however, functions differently. It synthesizes single-stranded RNA during the transcription process. It required a holoenzyme to … Ver mais In 1956, the first DNA polymerase was discovered by Arther Kornberg. Both polymerases are important for a cell. Error in the function of the … Ver mais WebThe initiation rate is then determined by the type of promoter (i.e., its DNA sequence), the local DNA structure and concentrations of RNA polymerases and regulators. The total …
