Weight-mole conversion for DNA and protein
|
Nucleotic acids
1 µg of 1,000 bp DNA (sodium salt) = 1.52 pmol = 9.1 x 1011 molecules
1 pmol of 1,000 bp DNA (sodium salt) = 0.66 µg
1 µg of 1,000 bp double-stranded DNA (sodium salt) = 6.6 x 105 daltons
1 µg of 1,000 bp single-stranded DNA (sodium salt) = 3.3 x 105 daltons
1 µg of 1,000 bp of single-stranded RNA (sodium salt) = 3.4 x 105 daltons
Calculations based on ammonium salt salt will be slight different.
Average molecular weight per base-pair:
| No salt | 618 Dalton |
| Sodium salt | 662 Dalton |
| Ammonium salt | 652 Dalton |
DNA and Protein
1 kb of DNA = 333 amino acids of coding capacity = 37 kD
10 kD = 270 bp DNA
1,000 aa protein = 110 kD
