the cellular genome size of RGD3.0, the organism with a 473 genome, is 531kbp according to the paper. this means that the genome encompasses ~531,000 nucleotides (base-pairs). for reference, the human genome encompasses approximately 3.3-billion base-pairs.

you can download the human genome from here http://hgdownload.soe.ucsc.edu/goldenPath/hg38/bigZips/hg38.... (it is recommended to use ftp, see: http://hgdownload.soe.ucsc.edu/goldenPath/hg38/bigZips/). it is an ~800mb download.

if it takes 800 mb to store 3.3 billion bases, i would assume it takes (531k / 3.3b) * 800 mb = 0.141 mb to store this genome.

Thanks! By the way, when you say "you can download the human genome", presumably this is the genome of a specific individual whose DNA was sequenced? What person is that?

[amphitoky]

no, it is a consensus sequence determined by sequencing the genomes of several individuals. i do not know how many individuals were sequenced for hg38, but hg37 was derived from 13 individuals according to [1].

genomic regions with higher variability between individuals are annotated separately and are not represented in the main chromosomal sequence, but can be aligned to it as such.

You can download Craig Venter's genome here:

However, the human "reference" genome (the updated main product of the Human Genome Project) is a patchwork of about 20 donors' genomes. Many(most?) of the donors are anonymous volunteers from Buffalo, NY, USA.
