Italics: minimum and maximum values
Bp, base pairs; cm, centimeters (variation was calculated considering the uncertainty of the bp number per DNA helical turn [55]); pg, picograms; fg, femtograms; GC%, percentage of G (guanine), C (cytosine) and S (G or C) among certain bases
aThe total was obtained summing lengths and weights for the 24 types of human linear DNA molecules and used in order to proportionately calculate the length and weight of unplaced bases, improving whole genome calculation accuracy
bTotal for a male or female diploid cell, including a double complement of unplaced bases
