Eukaryotic genes contains 2 regions: “exons” and “introns”.
Exons – code for amino acids.
Introns - DO NOT . Fx?
During transcription, both E+I are copied from the DNA.
DNA sequence coding for proteins exons may be interrupted by non coding DNA i ntrons.
During RNA synthesis, non-coding sequences of base pairs needs to be subtracted from the coding sequences of a gene in order to transcribe DNA into (mRNA.) So that.. mRNA that leaves now consists of a continous coding region
