"The Genome Fully Predicts the Proteome"
Captions available
The idea
A genome does not fully predict its proteome, because alternative splicing and post-translational modification add diversity the DNA sequence alone does not fix.
In practice
Alternative splicing of one gene's pre-mRNA, per Bio 1331, produces more than one protein from a single sequence.
Where people slip
A genome sets which proteins are possible; splicing and modification, not the genome alone, determine which proteins a cell actually makes.
