What is the molecular weight of a gene and its length, if a protein with a molecular weight of 1500 g / mol is encoded in it?

one amino acid is 100 atomic mass units.
To find out the number of amino acids, divide 1500 by 100 = 15
One amino acid encodes three nucleotides, DNA is double-stranded.
means total nucleotides 15 * 3 * 2 = 90
Gene mass: 90 * 345 = 31050
And finally, the length of one nucleotide is 0.34 nm, which means 345 * 0.34 = 30.6
Answer: gene mass = 31050
gene length = 30.6 nm
