What might be the evolutionary advantage of genes being interrupted by introns?

An intron is an area in the DNA that has not been translated into a protein. One evolutionary advantage of genes being interrupted by introns is that it reduces the occurrence of genetic mutations.

∙ 13y ago1. dilutes the effects of mutations (because there's a chance of mutation hitting a non-coding region instead of a coding region)
2. improve expression of exons (through IME, intron-mediated enhancement)

∙ 10y agothe evolutionary advantages of genes being interrupted by introns are that they might not be able to make mRNA and tRNA

What is evolutionary heritage?
Evolutionary heritage means the history of life before the species being studied. For example, what sort of life came before humans, horses, birds and even fish. The progression of one species into another until the species seen today.
What could changes in our ancestors' teeth tell us about the evolutionary history of humans?
One simple thing is diet. Large molars and massive jaws indicate that rough vegetable matter the required heavy mastication was being consumed. Australopithecus robustus, for instance.
What is meant by the term mechanical advantage?
A lever is a very useful tool that lets us exchange weight for distance. For example (theoretically) if you had to move a 200 pound sack into a car, but couldn't lift it, you could divide it into 8 parts, each being 25 pounds, and move each one individually into the car. It would be easy, however it would take more distance (lifting into the car 8 times instead of 1)
The mechanism by which evolution occurs is called?
AnswerNatural selection is the mechanism put forward by Darwin as one of the two essential mechanisms for evolution, the other being random mutation (which Darwin described as inheritable variation, not knowing about genes at the time).The modern evolutionary synthesis includes genetic mutations as the mechanism which provides variations upon which natural selection can act.
What do biologists base their in belief in evolutionary theory?
It is the only theory presented that explains the existence of different species and the different versions/implementations within a species. It is based on various scientific based studies made over time by accepted scientists. All other beliefs are based on religious beliefs, mythology, superstition or suggestions of alien intervention. Although the evolutionary theories have flaws (many flaws) and contradictory evidence, no other scientific based alternatives have been presented with enough evidence to warrant being accepted and until that occurs, the currently accepted beliefs will prevail, as will the religious beliefs, mythology, superstition and suggestions of alien intervention.
What might be one evolutionary advantage and one disadvantage to being a specialist?
clouds are mad of fog and rain
Why was the Hanukkah interrupted?
There is no tradition of the holiday of Hanukkah being interrupted.
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.
What might be the evolutionary advantage of having animal-like and plant-like characteristics in the same organism?
Being a heterotroph when high energy food stuff was available and being an autotroph when sunlight was all that could be obtained.
How is RNA altered after it is transcribed?
poly-A tail 7-methylguanine cap introns being removed (splicing)
What are the advantages of the evolutionary model?
In the context of biology, the advantage of evolutionary theory is that it explains the patterns we find in the diversity of life. Being able to explain these patterns also allows us to predict future patterns with some confidence, which in turn may be useful in such fields as agriculture, public health, medicine.
The principal problem with inserting an unmodified mammalian gene into the bacterial chromosome and then getting that gene expressed is that?
bacteria cannot remove eukaryotic introns; bacterial dna does not contain introns like eukaryotic genes do so they had to be removed before being added to the plasmid.
What are the evolutionary advantages of the vascular system?
being taller in height
What is a advantage of being an architect?
Advantage versus what?
Why haven't you spoken to your wife in 25 years?
Because she doesn't like being interrupted
Which current circles the entire globe without being interrupted by a continent?
Antarctic Circumpolar Current.
What is Heterogeneous nuclear DNA?
Pre-mRNA. It is the mRNA that is synthesized in the nucleus of eukaryotes. After being synthesized, this mRNA is processed, so that introns, noncoding, DNA is removed.
