WebFor haploid yeast cells, the mean nuclear volume is 3 μm 3 (BNID 104709). With a genome length of 12 Mbp (BNID 100459), the DNA takes up roughly 0.3 % of the nuclear volume. We can arrive at this estimate based on the rule of thumb that a base pair has a volume of ≈1 nm 3 (BNID 103778)) and thus the DNA occupies roughly 0.01 μm 3.
