What is an exon and intron?
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.
What are two significant differences between introns and exons?
Difference between Introns and Exons
| Introns | Exons |
|---|---|
| DNA bases found in between exons | DNA bases that are translated to proteins |
| Introns are removed in the nucleus before the mRNA moves to the cytoplasm | Mature mRNA contains exons and moves to the cytoplasm from the nucleus |
