Molecular Weights (MW)

 

Average MW RNA nucleotide = 340 Daltons         

MW ss RNA = (# nucleotides) x 340

 

Average MW RNA basepair = 680 Daltons

MW ds RNA = (# nucleotides) x 680

 

Average MW DNA nucleotide = 330 Daltons

MW ss DNA = (# nucleotides) x 330

 

Average MW DNA basepair = 660 Daltons

MW ds DNA = (# basepairs) x 660

 

Average MW of an amino acid = 110 Daltons

Average MW of a protein = (# of amino acids) x 110

 

 

Conversions for Protein and DNA Size and Weight

 

Average molecular weight of an amino acid = 110 Daltons

1 kg of DNA = 333 amino acids = 37 kDa protein

10 kDa protein = 270 bp DNA

100 pmol of 1 kDa protein = 100 ng

 

1 kb of ds DNA = 6.6 x 10/5 Daltons

1 kb of ss DNA = 3.3 x 10/5 Daltons

1 kb of ss RNA = 3.4 x 10/5 Daltons

 

Average weight of a nucleotide = 330 Daltons

1 µg of 1000 bp DNA = 1.53 pmol (3.03 pmol of DNA ends)

1 pmol of 1000 bp DNA = 0,66 µg

 

1 A260 unit of ds DNA = 50 µg/ml

1 A260 unit of ss DNA = 33 µg/ml

1 A260 unit of ss RNA = 40 µg/ml
