What happens to RNA polymerase ll after it has completed transcription of a gene?

RNA polymerase matches a base on the DNA to a RNA nucleotide(by complementary base pair binding) and then adds that new nucleotide to the elongating mRNA strand.
A messenger RNA strand is released from RNA polymerase. This strand is a complementary copy of the DNA message and can now move to the process of translation

∙ 12y agoIt is free to bind to another promoter and begin transcription

∙ 12y agowell rna polymerase only binds to certain parts of specific base sequnces in dna, the rna polymerase simply just stays in the nucleus to keep doing its job. it doesnt neccesairly go anywhere.

What happens first during transcription?
RNA polymerase reaches the beginning of the gene
How would RNA polymerase be affected if the repressor protein were not bound to the proper site on a gene?
it will prevent the transcription of rNA polymerase
In the binding of RNA polymerase to a gene requires the aid of a transcription factor?
Like prokaryotes, eukaryotes must regulate gene expression. This is accomplished primarily by controlling when RNA polymerase binds to the beginning of a gene. This binding cannot take place in eukaryotes without the aid of transcription factor.
What happens right before transcription begins?
RNA polymerase is guided to the correct place -apex
How does dense packing of DNA in chromosome prevent gene expression?
If the gene is obscured and hidden by folds or heavily methylated, RNA polymerase has a difficult time getting to the promoter region to initiate transcription. If the polymerase can't get there, then the gene is not transcribed and translated to a protein.
What happens at the of transcription?
The transcription process stops.mRNA detaches and moves to the ribosomesTranscription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.
What happens first during transcription?
RNA polymerase reaches the beginning of the gene
What happens at end of transcription?
The transcription process stops.mRNA detaches and moves to the ribosomesTranscription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.
What is last steps during transcription?
RNA polymerase reaches the end of a gene.

it will prevent the transcription of rNA polymerase
What steps happen lasts during transcription?

When transcription begins the enzyme is called?
the RNA polymerase attaches to the promoter and transcribes the gene in messenger RNA, or mRNA
What happens right before transcription begins?
RNA polymerase is guided to the correct place -apex
How does the repressors protein prevent transcription?
By attaching to the a region of the gene called operator thus blocking RNA polymerase so that the gene is not transcribed.
What happens at the end of transcriptions?
The transcription process stops.mRNA detaches and moves to the ribosomesTranscription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.
