deoxyribonucleotide triphosphates (dNTPs)

The triplet code

Alternative Splicing of mRNA

• One gene can code for more than one protein

• Exons can be spliced together into a variety of different mRNAs.

Eukaryotic gene model: spliced genes

Posttranscriptional modification

5’-CAP, polyA tail, splicing

Open reading frames Mature mRNA contains ORF

All internal exons contain open “read-through”

Pre-start and post-stop sequences are UTRs

Multiple translates One gene – many proteins via alternative splicing
