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.

What are intron-exon borders?

Intron-exon borders are the junctions between introns (non-coding regions) and exons (coding regions) within a gene. These borders are important for the process of splicing during gene expression, where introns are removed and exons are joined together to form a mature mRNA transcript. The specific sequences at these borders help determine where splicing occurs.


What is meant by primer needs to span exon-exon junction?

so that the primers for target mrna you are tyring to amplify for q-pcr/pcr does not also amplify genomic dna which might be contamination from your purification, because the gDNA will not be amplified due to the intronic sequence (primer wont bind) and will only bind the exonic mrna sequence


Are promoter a part of an intron?

Promoters are not part of an intron. Promoters are specific DNA sequences located upstream of a gene, which are responsible for initiating the transcription process. In contrast, introns are non-coding sequences found within a gene that are removed during RNA processing before the mature mRNA is translated into a protein.


What is an intervening sequence of DNA that is not expressed called?

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.


What is an exon's role in DNA?

The exon codes for the opening sequence of DNA for protein synthesis. It is a sequence of nucleotides that code for the RNA to begin transcription of the DNA to RNA protein.

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


Are both intron and exon regions are transcribed into the primary transcript?

Yes, both intron and exon regions are transcribed into the primary transcript during transcription. However, only the exons are retained in the processed mRNA after introns are removed through the process of splicing.


What determined which proteins a cell make?

The answer is "DNA". It depends on the parts of the DNA that are activated and what part of the RNA-model is an intron or an exon. Only the exons get copied as RNA goes to the ribosomes, where proteins are made.

What is the definition of the word intron?

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.

Why do eukaryotes have introns in DNA?

As you might know, introns DNA is something you can called 'Junk Fragments'. It didn't contain any information. So its function as a protection to the coding fragment (exon...maybe i misspell it ). DNA is subjected to many kind of mutation caused by chemical compounds or physical cause (gamma rays, for example). With Intron, when there's a mutation, there's a high probability that the one which subjected to the mutation is intron not exon. This way, eukaryote cells might survive from genetic mutation. Human has a large number of intron in one gene. It cause human to survive from many kind of mutation.
