One of the DNA strands has a molecular weight of 124,200. Determine the mass of the protein encoded in this DNA molecule if the average molecular weight of one amino acid is 100 and one nucleotide is 345.
Proteins are made up of amino acids.
1) One amino acid is encoded in three DNA nucleotides.
Having found out the number of nucleotides and triplets, we find out the number of amino acids.
124200/345 = 360 nucleotides.
360/3 = 120 amino acids are encrypted in this chain.
2) To find the mass of a protein, you need to multiply the number of amino acids by their molecular weight:
120 * 100 = 12000. That is how much the protein encoded in this DNA molecule will weigh.
