Comments p.2/10 bottom paragraph:"Using information on the typical mass per cell for each domain and group and the genome size, [investigators] estimate the total amount of DNA in the biosphere to be 5.3×10^31 (±3.6×10^31) megabase pairs (Mb) (Table 1). This quantity corresponds to approximately 5×10^10 tonnes of DNA, assuming that 978 Mb of DNA is equivalent to one picogram [Dolezel et al., 2003 PMID: 12541287]."
