Why are introns removed during splicing?
During splicing, introns (non-coding regions) are removed and exons (coding regions) are joined together. For those eukaryotic genes that contain introns, splicing is usually required in order to create an mRNA molecule that can be translated into protein.
How can I win my enemy?
Win Over Enemies.
- Never disclose your intentions. Keep it exclusively to yourself your next move.
- Never act spontaneously.
- Become Superman.
- Act as if you are unaffected.
- When to attack?
- Be vigilant.
- Use of meditator.
- Use 3Ws against enemy.

How are exons joined together?
The 3′ end of the exon is cut and joined to the branch site by a hydroxyl (OH) group at the 3′ end of the exon that attacks the phosphodiester bond at the 3′ splice site. As a result, the exons (L1 and L2) are covalently bound, and the lariat containing the intron is released.
What are the exons?
Exons are coding sections of an RNA transcript, or the DNA encoding it, that are translated into protein. Exons can be separated by intervening sections of DNA that do not code for proteins, known as introns. Splicing produces a mature messenger RNA molecule that is then translated into a protein. …
What are tactics in war?
Tactics, in warfare, the art and science of fighting battles on land, on sea, and in the air. It is concerned with the approach to combat; the disposition of troops and other personalities; the use made of various arms, ships, or aircraft; and the execution of movements for attack or defense.
What does flanking mean in genetics?
A DNA sequence located adjacent to a gene, either upstream from its 5′-end or downstream from its 3′-end.
Are introns or exons kept?
So a good mnemonic to help you memorize that is “exons are expressed.” So they’re kept in the final mRNA molecule, whereas “introns are in the trash.” So because they’re in trash, the introns are not in the final mRNA molecule.
How do you win a war?
There are other times when, after careful planning, it is best to surprise and overwhelm your enemy.
- Lose battles but win the war.
- Know your enemy.
- Overwhelm resistance with speed and suddenness.
- Control the dynamic.
- Hit them where it hurts.
- Defeat them in detail.
- Expose and attack your opponent’s soft flank.
What happens if introns are not removed?
Not only do the introns not carry information to build a protein, they actually have to be removed in order for the mRNA to encode a protein with the right sequence. If the spliceosome fails to remove an intron, an mRNA with extra “junk” in it will be made, and a wrong protein will get produced during translation.
What is a flanking sequence tag?
This “Flanking Sequence Tag” (FST) identifies the genomic location of the insertion, its orientation and, if both borders are retrieved, the length of any deletion that may have occurred in the genome.
What is in the 5 UTR?
The 5′ untranslated region (5′ UTR) (also known as a leader sequence, transcript leader, or leader RNA) is the region of an mRNA that is directly upstream from the initiation codon. This region is important for the regulation of translation of a transcript by differing mechanisms in viruses, prokaryotes and eukaryotes.
What are introns purpose?
Introns, from this perspective, have a profound purpose. They serve as hot spots for recombination in the formation of new combinations of exons. In other words, they are in our genes because they have been used during evolution as a faster pathway to assemble new genes.
What is a flanking strategy?
In military strategy, flanking is attacking the opponent from the side. It’s effective because the enemy’s strength is usually concentrated at the front. By attacking the side, you’re more likely to hit a weaker spot, one less defended – giving you an advantage. Flanking has never been more relevant than today.
Do all genes contain the same number of exons?
On average, there are 8.8 exons and 7.8 introns per gene. About 80% of the exons on each chromosome are < 200 bp in length.
Why is there no splicing in prokaryotes?
In prokaryotes, splicing is a rare event that occurs in non-coding RNAs, such as tRNAs (22). As such, splicing is not necessary in these genes. The remaining 5% of genes in yeast have either one intron or two introns, suggesting that pre-mRNA splicing in yeast is not as complicated, as it is in other species.
Why are exons called exons?
Exon. The parts of the gene sequence that are expressed in the protein are called exons, because they are expressed, while the parts of the gene sequence that are not expressed in the protein are called introns, because they come in between–or interfere with–the exons.
What is strategy and tactics?
Strategy defines your long-term goals and how you’re planning to achieve them. In other words, your strategy gives you the path you need toward achieving your organization’s mission. Tactics are much more concrete and are often oriented toward smaller steps and a shorter time frame along the way.
Why is flanking so effective?
Flanking is useful because a force’s fighting strength is typically concentrated in its front, therefore to circumvent an opposing force’s front and attack its flank is to concentrate one’s own offense in the area where the enemy is least able to concentrate defense.
What are flanking sites?
From Wikipedia, the free encyclopedia. The 5′ flanking region is a region of DNA that is adjacent to the 5′ end of the gene. The 5′ flanking region contains the promoter, and may contain enhancers or other protein binding sites. It is the region of DNA that is not transcribed into RNA.
