How to calculate protein size from dna sequence

Answer»

AAMC decided that we should know that an AMINO acid residue has an average weight of 110 Da which is equal to 110 g / mol for reference.

IN is a 288-residue protein so it weights about 288 * 110 Da = 31680 Da. They WANT the weight of a tetramer of IN, which is composed of 4 IN UNITS. 31680 Da * 4 = 126,720 Da which is about 128 KDA.
