i haven’t found an implementation of the first one. the second targets javascript and should be available in node/chromium at some point. running /(a+)*b$/.test("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaba") in my browser console still makes the fans spin for 10 seconds, so i’m fairly sure it hasn’t shipped yet. without implementations and benchmarks to compare against, i can only comment on the theoretical differences.

In 1975, Sanger published his own DNA sequencing method alongside laboratory technician Alan Coulson, called the “plus and minus” technique. First, scientists mixed the DNA strand to be sequenced with an enzyme, DNA polymerase, as well as a primer, three normal dNTPs and one radiolabeled dNTP. Radiolabeled nucleotides are incorporated into growing DNA strands just like normal nucleotides, but are tagged with radioactive isotopes, such as phosphorus-32 or sulfur-35, so they can be detected using radiation-measuring equipment.
