The 5' and 3' Untranslated Regions

Video not yet published

State

A mature mRNA's untranslated regions flank the coding sequence, upstream of the start codon and downstream of the stop codon.

Show

The 5' region sits between cap and start codon; the 3' region sits between stop codon and poly-A tail.

Watch for

An untranslated region is still transcribed and spliced with the mRNA — only its translation into protein is what it lacks.
