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.

Does intron removal take place in the nucleus?
Yes, intron removal takes place in the nucleus. In eukaryotic cells, the process of RNA splicing, which involves the removal of introns from pre-mRNA, occurs in the nucleus before the transcript is transported to the cytoplasm for translation.
What is cut out of RNA molecules?
Introns are cut out of RNA molecules. Extrons are "spliced" together afterwards. Think of a long strand that is white with blue on the ends. The white of the strand is the intron, while the blue color are the extrons. The white color or the "intron" is cut out, and then the two blue strands merge together known as the extrons splicing together.
What is intro splicing and what does it allow the cell to do?
Is the removal of introns (non-coding) from a the strand of a newly formed messenger rna. Thus enabling it to carry out its function. It allows cell to translate some the messages into amino acids.
Can a single protein have multiple genes?
Yes. A protein produced by multiple genes are cased by fusion genes. Usually a protein is translated from a mRNA which is transcribed from a DNA. After transcription, RNA is rearranged by so-called RNA splicing in which some of short sequences are selected(Exon) or deleted(Intron). During the splicing two different genes can join together and it is called trans-splicing. After trans-splicing, mRNA is translated into a protein, so the protein has two genes. Most cases these fusion genes are oncogenes which cause Cancerous diseases.
What are the introns and exons?
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.
What is self splicing?
Intron that itself is the source of the enzymatic activity necessary for it removal. Splicing mechanism of pre-mRNA involving group I introns.
What is the definition of the word intron?
The definition of the 'intron' is part of the DNA sequence within a gene. It is the sequence within a particular gene that is removed during the RNA splicing process.
Does intron removal take place in the nucleus?
Yes, intron removal takes place in the nucleus. In eukaryotic cells, the process of RNA splicing, which involves the removal of introns from pre-mRNA, occurs in the nucleus before the transcript is transported to the cytoplasm for translation.
Small pieces of DNA that is edited out of the mRNA message before it is expreeed?
Small pieces of DNA that is edited out of the mRNA message before it is generated is a intron. It is removed by the RNA splicing.

Where does RNA editing occur in the cell?
mRNA processing occurs in the nucleus itself. This is because the mRNA processing involves adding the 5' cap and the poly-A tail. These features must be done before the mRNA is released into the cytoplasm because they help prevent it from being digested and harmed by the cell's own enzymes.
