Write a program that asks the user for a gene name and the number of
nucleotides in its coding sequence (namely the part in its cDNA that translate to protein,
from initiation to stop codon);
calculates the number of amino acids in the resulting protein and its estimated
molecular weight (in kilodaltons); and prints the results, including the gene name,
on the screen.
(For non-biologists: each amino acid is coded by 3 nucleotides)
