Exon DNA encodes for the RNA included in the final mRNA transcript that encodes for proteins. Intron DNA is found within exons, but is spliced out as the mRNA molecule is processed.

∙ 15y agoThe difference between exons and introns is that exons are codes of proteins, while introns are not involved with the coding for proteins.

What is the significance of introns and extrons?
a. Functionali. Intronsmay control gene activityii. Alternate splicing can give >1 protein from the same geneb. Evolutionaryi. Exons code for functional domains of proteinsii. Widely spaced functional components allows recombination č newproteins
What are non-coding segments of DNA?
this is the correct answer i promise exonsIt's right ^^ It's not introns because introns do not code.
What is the mRNA sequence splicing?
Eukaryotic genes have regions called "introns" and "exons". Exons code for polypeptides (often specific domains or motifs), while introns don't code for anything (that we know of) and are removed. mRNA splicing is the process where an mRNA molecule is cut up (usually by the "spliceosome") to remove the introns from an mRNA message. This is advantageous for us eukaryotes because we can recombine exons in different orders, and even combine exons from different genes to generate many proteins from a smaller number of genes.
What happens to the introns and exons during transcription?
After transcription, the mRNA is processed by the spliceosome, which splices out the introns (because introns are not part of the coding sequences for protein), and "stitches" the exons together to form the final transcript that is sent to the ribosome for translation.
What makes premature mrna and mature mrna different?
The first (primary) transcript from a protein coding gene is often called a pre-mRNA and contains both introns and exons. Pre-mRNA requires splicing (removal) of introns to produce the final mRNA molecule containing only exons
Which type of cell does not possess introns and extrons and produces polycystronic mRNA?
A prokaryotic cell.
What is cut out of RNA molecules?
Introns are cut out of RNA molecules. Extrons are "spliced" together afterwards. Think of a long strand that is white with blue on the ends. The white of the strand is the intron, while the blue color are the extrons. The white color or the "intron" is cut out, and then the two blue strands merge together known as the extrons splicing together.

Which part of the DNA molecule contains the genetic information used to make proteins?
The part of the DNA molecule that carries the genetic information is called the gene. It is the basic unit of heredity. The nucleotide base sequence encodes information. The bases of A,T and C,G code for the order of an Amino Acid which are the proteins. These four bases form millions of combinations that code for all the genetic material in a cell. These structures form the rungs of the ladder. DNA contains two different types of genes, known as introns and extrons. Extrons code for protein synthesis, and introns, as far as we can tell, play a role in determining when specific extrons will be expressed (which is to say, when they will actually be used for protein synthesis) and when they will remain dormant. Almost, the 4 types of nucleotides are "read" in groups of 3 to make 1 codon. Other than a start and stop codon, the rest are translated into amino acids. Those acids become proteins which are then made into genes, or cells of some kind.
When was Introns - album - created?
Introns - album - was created on 2006-03-13.
What are the introns and exons?
An intron is a DNA region within a gene that is not translated into protein. After intron splicing (ie. removal), the mRNA consists only of exon derived sequences, which are translated into a protein.
Why are introns copied and then removed from the RNA sequence?
Introns were copied and then removed from the RNA sequence because they were placeholders.
What is the role of introns in gene regulation?
Introns are removed through RNA splicing. They don't play a role.
Do mitochondria have introns?
No, prokaryotes do not have introns, and therefore do not do RNA processing. However, eukaryotes do.
Why do the introns have to br removed?
Introns are the non-coding parts of the gene. If you didn't remove introns, the wrong protein may be produced because they allow more than one protein to be produced from a single gene.
Which one exons or introns is spliced out when primary RNA is processed?
The introns are the sections which are spliced out to create the mature form of mRNA.
What is the small pieces of DNA that are edited out of the mRNA message before it is expressed?
During the transcription, when the mRNA is being processed, the introns are removed and the exons are connected together.
