Exons, after the introns have been cleaved.
Messenger RNA.
Exons
The introns are the sections which are spliced out to create the mature form of mRNA.
mRNA is a short term intermediate and once processing is complete mRNA dissolves. During processing mRNA becomes degraded as it reads the codons.
mRNA (and other RNA) molecule is built during transcription of DNA. mRNA transcript undergoes for processing to become mature. They transported to cytoplasm for the protein synthesis.
The only reason why mRNA is transcribed is so it can be translated. All existing mRNA are translated and afterwards are broken down or are spliced for different uses.
post transcriptional modifications such as cutting and splicing of exons!
During mRNA processing, non-coding regions of the transcript are spliced out. These regions are called introns. Coding regions are called exons.
introns ... exons.
the spliced exons are rejoined together and form a smaller mRNA.
Introns are cut out and then the exons are spliced together.
Introns
1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added. 1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added.
noncoding
in prokaryotes only self spilicing and tRNA splicing are present there is no splicosomes are present.
The introns are the sections which are spliced out to create the mature form of mRNA.
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.
mRNA is a short term intermediate and once processing is complete mRNA dissolves. During processing mRNA becomes degraded as it reads the codons.
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.
