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.

Mutations in introns are less likely to affect phenotype then mutation in exons?
mutation in exons are less likely to affect phenotype then mutation in introns because mutaion in exons are silent mutation
Are introns non-expressed?
Yes they are. Exons are expressed.
Spliced together during mrna processing?
Exons, after the introns have been cleaved.
What the remaining pieces called that are spliced together?
Introns, exons
What is the difference between exons and introns?
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?
In eukaryotes only exons are translated?
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)

Are introns non-expressed?
Yes they are. Exons are expressed.
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.

Name the sections of eukaryotic genes that are transcribed and translated?
introns and exons
What type of RNA holds information of both introns and exons?
mRNA
Are sense regions for of DNA introns and nonsense regions exons?
yup
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.
How do introns and exons relate to RNA splicing?
Before the RNA leaves the nucleus, the introns are removed and the exons are joined together, producing an mRNA molecule with a continuous coding sequence. This process is called RNA splicing.
