What are the phases of transcription?
Initiation - Polymerase III, binds and unwinds DNA, transcription begins. Elongation - Base pairng occurs polymerase I, binds the new strands of mRNA. Termination - New mRNA released.
Difference between DNA replication and transcription?
1. Replication is the duplication of two-strands of DNA. Transcription is the formation of single, identical RNA from the two-stranded DNA. 2. There are different proteins involved in replication and transcription. 3. In replication, the end result is two daughter cells, while in transcription, the end result is a protein molecule. 4. In transcription, DNA serves as the template for RNA synthesis.
During DNA replication DNA polymerase lands at origination sites and forms?
DNA polymerase is instrumental in DNA elongation as it catalyzes the addition of deoxyribonucleoside triphosphates to the 3 prime end hydroxyl group of the DNA chain. DNA polymerase binds on the origin of replication, and forms a pre-replication complex with other proteins. The replication complex unwinds DNA during replication
What event in transcription initiation likely occurs last?
The binding of RNA polymerase to the promoter sequence is the likely event that occurs last in transcription initiation. This binding allows for the initiation of RNA synthesis and the subsequent elongation of the RNA molecule.
Transcription follows the same base-pairing rules as DNA replication except for cytosine which has a different partner?
This is false transcription does not follows the same base-pairing rules as DNA replication except for cytosine which has a different partner. Transcription begins with an enzyme called RNA polymerase.
What are the phases of transcription?
Initiation - Polymerase III, binds and unwinds DNA, transcription begins. Elongation - Base pairng occurs polymerase I, binds the new strands of mRNA. Termination - New mRNA released.
What is the order of events that occur in transcription?
RNA polymerase binds to DNA Elongation Termination

What are the two jobs that RNA polymerase performs?
transcription: produces RNA, initiation and elongation of RNA chains from a DNA template
During DNA replication DNA polymerase lands at origination sites and forms?
DNA polymerase is instrumental in DNA elongation as it catalyzes the addition of deoxyribonucleoside triphosphates to the 3 prime end hydroxyl group of the DNA chain. DNA polymerase binds on the origin of replication, and forms a pre-replication complex with other proteins. The replication complex unwinds DNA during replication
The correct sequence of the events of transcription is?
RNA polymerase reaches the beginning of a gene.
How does transcription differ from DNA replication Describe at least four differences?
DNA replication produces a complimentary DNA strand. Transcription produces a complimentary mRNA strand. The major enzyme that carries out DNA replication is DNA Polymerase III (in prokaryotes). The major enzyme that carries out transcription is RNA Polymerase. DNA replication results in two copies of the DNA. Transciption does not affect the DNA - it simply re-anneals (re-joins) after the process. In DNA replication the complementary base to A is T. In transcription the complementary base to A is U.
What event in transcription initiation likely occurs last?
The binding of RNA polymerase to the promoter sequence is the likely event that occurs last in transcription initiation. This binding allows for the initiation of RNA synthesis and the subsequent elongation of the RNA molecule.
Transcription follows the same base-pairing rules as DNA replication except for cytosine which has a different partner?
This is false transcription does not follows the same base-pairing rules as DNA replication except for cytosine which has a different partner. Transcription begins with an enzyme called RNA polymerase.
Is DNA transciption is another word for DNA replication?
They are completely different processes in the central dogma. DNA replication is the replication of DNA into DNA by DNA polymerases. Trancription is the transcription of DNA into RNA by RNA polymerase.
The reaction catalyzed by DNA polymerase is?
There are different types of DNA polymerase depending if it's from a eukaryotic or prokaryotic cell each performing specific tasks. Basically DNA polymerase catalyzes the formation of a polymer, a DNA strand, from many monomers, deoxyribonucleotides.
How does elongation happen?
The polymerase moves downstream, unwinding the DNA and elongating the RNA transcript from the 5' to 3' ends. In the wake of transcription, the DNA strands reform a double helix.
