How many amino acids does the protein contain?
A gene has four exons with lengths in base pairs (bp) as follows.
Exon 1, transcription start to just before ATG translation initiation codon: 219 bp
Exon 1, from ATG initiation codon to end of segment:282 bp
Exon 2, all: 201 bp
Exon 3, all: 93 bp
Exon 4, beginning through (and including) TGA stop codon: 177 bp
Exon 4, from just after TGA stop codon to polyadenylation site: 405 bp
