why is it that the DNA polymerase needs 4 deoxyribonucletides else RNA polymerase need only 2NTP
DNA Polymerase synthesizes a DNA strand and used in DNA replication while RNA Polymerase is used during transcription to synthesize the mRNA strand. In contrast with the DNA polymerase, RNA polymerases donot necessarily require the so called primer to start the process and they actually have no proofreading systems.

why does dna polymerase only tun 3' to 5' direction? ON) Why does DNA polymerase only run in the 3' to 5' direction? A - A - IX E 1 E 1 1 x X, - Paragraph 12pt -
Which of the following occurs ONLY in eukaryotic cells and NOT in prokaryotic cells? RNA polymerase binds to the DNA template at the promotor sequence of the gene RNA polymerase is capable both of unwinding and separating the DNA helix - hence displaying part of the DNA template for transcription - and of catalyzing the formation of phosphodiester bonds. RNA polymerase pairs up Uracil (U) in the elongating RNA strand with Adenine (A) in the DNA template RNA polymerase pairs...

RNA polymerase releases the DNA template. Initiation Elongation Termination A process called clearance or escape. The RNA polymerase holoenzyme binds to the promoter A process called clearance or escape. Reaching a terminator sequence causos formation of phosphodiester bonds to stop. The RNA polymerase holoenzyme is formed. Once bound to the promoter, RNA polymerase begins to unwind the DNA. New nucleotides are added to the 3' end of the growing RNA transcript. The RNA-DNA hybrid within the transcription bubble dissociates New...
Compared to RNA elongation by RNA polymerases, DNA elongation by DNA polymerase requires an additional reaction component. Which is appropriate for fulfillment of this requirement? Select one: a. a primase is needed for the biological DNA replication. b. a short DNA primer is necessary for PCR. c. a host tRNA is used for the synthesis of DNA by viral reverse transcriptase. d. All of these e. None of these
the specific dna regions where an RNA polymerase attaches and initiates RNA synthesis are called?
Question 29 Which of the enzymes below would nearly all RNA viruses have? DNA-=dependent DNA polymerase Lysozyme RNA-dependent RNA polymerase Reverse transcriptase ATP synthase
Bacteria contains only one RNA polymerase. Both bacteria and eukaryotes only have one RNA polymerase. Question 26 Which of the following is part of the promoter recognized by bacteria RNA polymerase? -10 region -35 region Both -35 regiona dn -10 region. -40 region
1) RNA polymerase has low affinity to mRNA – why is that? 2) Initially, RNA polymerase makes a few short transcripts, why?
The primary reason leading and lagging strand synthesis is different is because O DNA polymerase only adds new nucleotides to the 3’end of a nucleic acid O DNA polymerase only adds new nucleotides to the 5' end of a nucleic acid O RNA polymerase only adds new nucleotides to the 3' end of a nucleic acid O RNA polymerase only adds new nucleotides to the 5' end of a nucleic acid
