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.

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.
RNA splicing involves the?
removal of introns from the molecule :)
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 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 are introns and extrons and how are they different?
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.

What is the process called which removes introns from RNA?
RNA splicing
Do mitochondria have introns?
No, prokaryotes do not have introns, and therefore do not do RNA processing. However, eukaryotes do.

Spliced together during mrna processing?
Exons, after the introns have been cleaved.
What type of RNA holds information of both introns and exons?
mRNA
What is the role of introns in gene regulation?
Introns are removed through RNA splicing. They don't play a role.
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
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.
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 might be an advantage of RNA splicing?
the spliced exons are rejoined together and form a smaller mRNA.
