why is it that the DNA polymerase needs 4 deoxyribonucletides else RNA polymerase need only 2NTP
Homework Answers
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.

When comparing prokaryotic RNA polymerase with eukaryotic RNA polymerase II, only eukaryotic RNA polymerase II begins by binding to the gene's promoter region. uses sigma factor to specifically recognize promoter consensus sequences. relies on a collection of transcription factors to facilitate its binding to the DNA. begins transcription at numerous origins of replication. uses a double-stranded DNA template to produce a single-stranded RNA copy.

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 end replication problem arises because: a) DNA polymerase can only add nucleotides in one direction b) helicases cannot unwind the end of chromosomes because they are not AT rich sequences but TG rich c) The replisome holoenzyme isn’t properly recruited to the end of chromosomes d) Primers are made of RNA e) DNA polymerase needs a clamp to synthetize DNA until the end of chromosome and without this it falls off the end
