Intron Latest News
Scientists visually tracked an RNA intron jumping from a predator to its prey, revealing insights into gene transfer across species.
About Intron
- In some genes, not all of the DNA sequence is used to make protein.
- Introns are noncoding sections of an RNA transcript, or the DNA encoding it, that are spliced out before the RNA molecule is translated into a protein.
- The sections of DNA (or RNA) that code for proteins are called exons.
- Following transcription, new, immature strands of messenger RNA, called pre-mRNA, may contain both introns and exons.
- The pre-mRNA molecule thus goes through a modification process in the nucleus called splicing during which the noncoding introns are cut out and only the coding exons remain.
- Splicing produces a mature messenger RNA molecule that is then translated into a protein.
- Introns are also referred to as intervening sequences.
- The length of introns differs among species and genes in the same species; mammals and flowering plants have multiple introns and are longer than exons.
- Introns may contain sequences that regulate how genes are expressed or transcribed and how mRNA is processed.
