Scientists are still learning so much about genetic processes.

Scientists are still learning so much about genetic processes. A fascinating recent example of this is the discovery by European researchers, that so-called transcription factors, the chemical compounds which turn genes ‘off’ and ‘on’, don’t function as single molecules, as previously believed, but as tiny spheres about 30 nanometres in diameter, which are shaped like footballs but are 10 million times smaller. “The textbooks all suggested that single molecules were used to switch genes on and off,” explains lead researcher Mark Leake, “not these crazy nano footballs that we observed".
