Exons are the DNA sequences that code for proteins. Introns are involved however they dont carry the genetic information that exons carry, the variation provides for revolutionary flexibility allowing cells to shuffle exons between genes to make new ones.
A great way to remember which is which is Exons (sounds like Executives, like in a business) have the information and introns (sounds like the interns of a business) dont know anything; exons and inrons, executives and interns. Easy huh?

An intron is DNA code between exons. It will not be used in protein synthesis and will be removed. The exons will be the code that forms proteins.
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.
mutation in exons are less likely to affect phenotype then mutation in introns because mutaion in exons are silent mutation
Yes they are. Exons are expressed.
many biologist think that this organization of genes add evolutionary felixablity . Each Econ protein adds a different part of a protein by having introns and Exons fellas can occasionally shuffle exons between genes and make new ones .
Exons, after the introns have been cleaved.
Exons code for amino acids (they are usable codons) Introns code for nothing.
Correct. The mRNA transcibed from the DNA in the nucleus has both exons and introns; the introns are taken out and the exons are left in. The mended exons exit the nucleus and the introns stay in the nucleus. Only the exons are translated at the ribosomes. (In Eukaryotic cells only)
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.

For one; there was a Time when there was no such thing as an intron, all genetic material was expressed. Having said that, as Time went by, the ratio of [expressed] exons to [suppressed] introns shrank.
Yes they are. Exons are expressed.
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.
