-RNA transcript is generated at an unwound stretch of DNA
- RNA nucleotides incorporated are complementary to the template
- DNA strands rejoin
- termination side

4

Exon

kept codes for protein
become part of final mRNA

5

Intron

removed
"in the way"
don't encode info

- modified GTP
- facilitates translation

7
