No
An intervening sequence of DNA that is not expressed is called an intron. Intron sequences are removed during RNA processing, while the remaining expressed sequences are known as exons.
intron
Intron is a DNA sequence which has no meaningful codes, but in other hand exons codes for the meaningful proteins. So those exons are collectively made as mRNA, from that cDNA would be synthesized to clone them in rDNA technology.
Enhancers are at considerable distances from the promoter and can be moved or inverted and still function. Promoter-proximal elements are close to the promoter and their position and orientation must be maintained.
No. Those are two different parts of pre-mRNA before the transcription is finished. The intron is the non coded region, and is therefore spliced out of the mRNA. The coding portions of eukaryotic genes are split in to two types of DNA, introns and exons. Only the exons code for the protein itself. The introns often contain control regions and are 'spliced out' in a process known as post-transcriptional modification. It's actually a little more complicated than that in practice, as some genes have exons which they sometimes include in the mRNA that goes for transcription and at other times they won't include those exons, they'll splice them out in the same way as they would an intron. An example of this would be the cartilage structural protein collagen II.
on a gene it can occur on the promoter, intron-exon borders, poly-A-tail cleavage sites and on the exon
The definition of the 'intron' is part of the DNA sequence within a gene. It is the sequence within a particular gene that is removed during the RNA splicing process.

No, the gene cassette is made up of the promoter, transgene and terminator.
The opposite of a promoter is a detractor, someone who undermines or speaks against something.

Transcription in a prokaryotic promoter starts at the DNA sequence called the "promoter region."

The SV40 promoter and the CMV promoter are both DNA sequences that control the expression of genes. The SV40 promoter is smaller and less efficient than the CMV promoter in driving gene expression. The CMV promoter is commonly used in research and biotechnology due to its high efficiency in promoting gene expression.
