Oswald Avery, Colin Munro MacLeod, and Maclyn McCarty, working with Streptococcus pneumoniae bacteria, by a process of elimination, removed bit by bit and repeated Griffith’s experiment until the bacteria were unable to transform, and thus isolated and identified DNA as the material of genes and chromosomes.
Nucleic acid polymers
In the nucleus of eukaryotic cells and inside the walls of prokaryotic cells long polymers encode the instructions for making every living organism on Earth.
If we were to tinker
Now we know how to flip the switches maybe we could cure cancer without trying to breed superkids. Maybe we could abolish sickle cells without making everyone the same.
