Introns
are a part of your genetics that are edited out when making mRNA
after transcription. The opposite are exons,
which are the "keeper" parts. A chunk of DNA, called a gene is read and copied (like a photocopy) into a disposable piece called mRNA.
This process is called Transcription. However, the mRNA
"photocopy" isn't ready for the next step, called Translation. It needs editing. Pieces are chopped out of it and the remaining pieces are 'stitched' back together. The chopped out (trash) pieces are called introns.
The remaining pieces (keepers) are called exons.
The edited mRNA
(made up of keeper exons
pieces) is now all ready. It leaves the nucleus so it can find a ribosome
and begin translation.
Introns stay IN the nucleus (trash).
Exons
get to EXIT the nucleus (keepers
that get to move on to the next step).
Introns - album - was created on 2006-03-13.
Introns were copied and then removed from the RNA sequence because they were placeholders.
Introns are removed through RNA splicing. They don't play a role.
No, prokaryotes do not have introns, and therefore do not do RNA processing. However, eukaryotes do.
Introns are the non-coding parts of the gene. If you didn't remove introns, the wrong protein may be produced because they allow more than one protein to be produced from a single gene.
The introns are the sections which are spliced out to create the mature form of mRNA.
During the transcription, when the mRNA is being processed, the introns are removed and the exons are connected together.
this is the correct answer i promise exonsIt's right ^^ It's not introns because introns do not code.
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.
snip out introns from mRNA.
yes
