One kilobase of mRNA fully translated gives a protein of about 330 amino acids.
This protein has a molecular weight of about 40,000 daltons.
The mass of the protein is about 6.7 x 10 -20 grams. (40,000 / 6 x 10 23 )
The volume of the protein is about 5.2 x 10 -20 cc = 52 cubic nanometers.
If the protein is spherical, its radius is about 2.3 nanometers.
The DNA that coded for this protein is about 2 nanometers by 340 nanometers.
