How octopuses, squid, and cuttlefish defy genetics' 'central dogma'

Octopuses, squid, and cuttlefish often do not follow the genetic instructions in their DNA to the letter. Instead, they use enzymes to pluck out specific adenosine RNA bases (some of As, out of the As, Ts, Gs, and Us of RNA) that codes for proteins and replace them with a differe … | Continue reading
