Comments p.3/10 bottom paragraph:"Information on DNA abundance can also be gleaned from the earth’s total organic carbon, which is estimated to be on the order of 2,000 Gt [BNID 111600]. DNA makes up a few percent of cellular carbon from literature estimates [investigators] chose a working value of 3% DNA in cellular organic carbon [primary sources], giving a total DNA quantity of 5.9 × 10^31 Mb." Gt=10^9 tonnes
