Who knows? It must be HUGE!

The US patent office is heavily bogged down with DNA/RNA sequences right
now. Part of the problem stems from the fact that some claims include
literally thousands of sequences and/or any combination of oligonucleotide
mixtures (i.e. degenerate oligos), making the prior art searches incredibly
time consuming (estimates for some applications have been in the 56
examiner-year range!). They are considering several options, including
increasing application fees for nucleotide sequences and setting a limit of
one sequence per application. I imagine the back-log will continue to grow
rapidly for the foreseeable future.
