No it does not a promoter is a binding site for RNA polymerase.
A piece of DNA which controls a trait is a gene variations of a gene are called alleles. If you mean "controls how much a particular trait is expressed" then you would be dealiung with the promoter region of a gene which is near the start and controls how strongly a gene is expressed.
There are three main parts of a gene. First, the promoter includes when and where the gene should be transcribed. Then, the coding sequence contains the instructions for making a protein. Last, the terminator indicates that the coding sequence is over.
Heterologous Expression systems are tools to find out whether a particular gene produces mRNA and/or protein and whether the protein produced is functional or defective. In these systems, we use the expression vectors in which cDNA of the gene of interest is clonned along with suitable promoter. When this gene is expressed through transcription by the formation of mRNA, then the resultant protein is formed by translation of mRNA.
A promoter <--- Gradpoint/NovaNet A promoter is located at the beginning of a gene. A promoter functions by facilitating transcription of that gene

No
a gene being expressed means it is shown, for example if you have the gene for brown eyes and the gene for blue eyes, only one can be expressed. if you have brown eyes that gene is expressed, if not the blue-eye gene is expressed.
No. If a gene is expressed, it is turned on.
No, the gene cassette is made up of the promoter, transgene and terminator.
The promoter
RNA is the expressed form of a gene (which is DNA encoded). By isolating RNA, it is possible to determine which genes were being expressed and to what relative (or even absolute) level.
