When does transcription begins prokaryotic cell?
In Prokaryotic Cells transcription and translation can occur simultaneously, but transcription happens after a transcription initiation complex has been formed.
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.
What is initiation in transcription?
So in Transcription there are three main steps: Initiation, elongation and termination. The one I'm focusing on is Initiation. In eukaryote, proteins called transcription factors mediate the initiation of transcription by RNA Polymerse II. A eukaryotic promoter commonly includes a TATA box, a nucleotide sequence containing "Thymine-Adenine-thymine-adenine", about 25 nucleotides upstream from the transcriptional start point.
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.
Which step in what procedure represents transcription?
Transcription is the process of synthesizing messenger RNA (mRNA) from DNA. It occurs in the nucleus of the cell and involves three main steps: initiation, elongation, and termination. The initiation step involves the binding of RNA polymerase to the promoter region of the DNA.
What are two differences between transcription and DNA replication?
# Transcription is copying a section of DNA (a gene) onto a mRNA molecule. Replication is the copying the entire DNA molecule. # Transcription does not require primer for initiation.DNA replication use primer for initiation. # RNA transcription, mRNA copy of the active stand of DNA helix is made this process is carried by different enzyme & result is a single of mRNA.DNA replication double helix of DNA is duplicated into two identical double helix which are also identical to the mother DNA, this process is carried by specific enzyme

What does Transcription in eukaryotes require in addition to RNA polymerase?
General Transcription Factors (GTF). TFIID (binds to DNA first at TATA box), TFIIA, TFIIB, TFIIF, TFIIE and TFIIH.

The correct sequence of the events of transcription is?
RNA polymerase reaches the beginning of a gene.
Does eukaryotic transcription begin before the promoter clearance?
No, Eukayotic transcription begins after promoter clearance. Promoter clearance just prepares the transcription initiation complex to begin elongation. Promoter clearance does not produce any functional gene.
What does the synthesis of a new strand of DNA begin?
Following the initiation of DNA replication, the first step is the synthesis of a short RNA primer.
What are the two jobs that RNA polymerase performs?
transcription: produces RNA, initiation and elongation of RNA chains from a DNA template
During DNA duplication primer called RNA primer why?
The initiation of the reaction is favoured energetically by formation of this RNA-DNA hybrid.This hybrid is more stronger than DNA-DNA hybrid
