What is first located on a gene?
A promoter <--- Gradpoint/NovaNet A promoter is located at the beginning of a gene. A promoter functions by facilitating transcription of that gene
Does a promoter determine whether a gene is expressed?
No it does not a promoter is a binding site for RNA polymerase.
When transcription begins the enzyme is called?
the RNA polymerase attaches to the promoter and transcribes the gene in messenger RNA, or mRNA
Which genectic information is a cue to where one gene begins and where one ends?
promoter
What is promoters and an operator together called?
Operon. It contains the promoter, operator, and the structural gene.
What is first located on a gene?
A promoter <--- Gradpoint/NovaNet A promoter is located at the beginning of a gene. A promoter functions by facilitating transcription of that gene
Which of the following statements best describes the promoter of a protein coding gene?
The promoter is a nontranscribed region of a gene.
Which of the statements best describes the promoter of a protein-coding gene?
The promoter is a nontranscribed region 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.
In the control of gene expression in bacteria a regulatory gene a has its own promoter?
No
Does a promoter determine whether a gene is expressed?
No it does not a promoter is a binding site for RNA polymerase.
Is DNA junk or not junk?
AnswerThere is junk DNA or non-coding DNA. This DNA is the segment before the promoter of a different gene.
Is vector a part of gene cassette?
No, the gene cassette is made up of the promoter, transgene and terminator.
Helps RNA polymerase recognize the start of a gene?
The promoter
When transcription begins the enzyme is called?
the RNA polymerase attaches to the promoter and transcribes the gene in messenger RNA, or mRNA
Where do gene mutations occur?
on a gene it can occur on the promoter, intron-exon borders, poly-A-tail cleavage sites and on the exon
What is a DNA promoters?
A Promoter is a region of DNA that facilitates the transcription of a particular gene.
