This shows the total number of nucleotides (letters of DNA) that have been registered in GenBank, a national repository. The data is from GenBank (visualized by some Wikipedians). Then number of nucleotides is graphed on a logarithmic scale, where a straight line means that the number of nucleotides that have been registered is increasing exponentially.

That is not correct. That is the number of basepairs/nucleotides in Genbank, not genes.

Great catch! I fixed it. Thanks.

It's actually the number of base pairs in the sequences in GenBank. While there are more than the 5 basic nucleotides, there aren't billions.

The number of nucleotides in a genome, if haploid, is equal to the number of base pairs. What you are writing about is the number of distinct nucleotides, which, while interesting, is not what GenBank tracks.
