Why are exons important?
Exons code for proteins. Exons are parts of DNA that are converted into mature messenger RNA.. From there, mRNA undergoes translation where mRNA is used to synthesize proteins.
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 happens before a RNA messenger is mature?
RNA is spliced (cut) in order to make it mature. This involves splicing out the introns and leaving the exons - these are the segments that code for a protein. This means that when mRNA leaves the nucleus, it only contains the segments that directly code for a protein.
Spliced together during mrna processing?
Exons, after the introns have been cleaved.
How is excision to make the completed mRNA accomplished?
post transcriptional modifications such as cutting and splicing of exons!

What is the primary transcript of eukaryotic genes?
the primary transcript usually has a exons and introns which need to undergo splicing to remove the introns and re-splicing to join the exons ..after this process the resulting mRNA is a mature mRNA.
What are the intervening sequence of RNA molecules that are cut out before the messenger RNA leaves the nucleus?
Introns are cut out and then the exons are spliced together.
What is the function of the spliceosome?
In eukaryotic organisms, genes consist of exons and introns. Exons are regions that are transcribed into mature messenger RNA, and eventually translated into protein. Interspersed within the exons are introns, regions of non-coding DNA. Introns must be removed from the initial transcript of mRNA before the final mature transcript is sent to the ribosome for translation into protein. This removal is done in a coimplex protein structure called the spliceosome. The spliceosome splices out the non-coding introns from the primary mRNA transcript, and stiches the exons back together into the mature mRNA transcript.

The introns are the sections which are spliced out to create the mature form of mRNA.
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
What is the role of the enzymes in cloning?
The role of arestriction enzyme is to remove the intronsto make a mature mRNA, so that the new mRNA codes for the making of a single protein. The restriction enzyme will only leave the exons to make the mRNA more shorter, and therefore easier to insert into plasmids

What is intron splicing and what does it allow the cell to do?
Intron excising. When the messenger RNA is first transcribed the genes it is transcribed from have areas of sense, exons, and areas of " nonsense " ( not really, but let's keep it simple ) called introns. So the pre-mRNA has a complex called the spliceosome attach to it and this excises the introns, then spices the exons together to make mature mRNA. So a cell can send a clean gene copy to the ribosomes for translation.
