Intron

MRNA (noncoding)

Start in DNA during transcribed into premRNA then removed through RNA splicing not a part of the final mRNA they are degraded

Exons

MRNA (coding)

Transcribed into premRNA some are removed but the remaining join together to form a continuous coding sequence are a part of the final mRNA
