Life from non life ping!

Yes, now the new word is “morph.” We all descendantly, from these two meter backstoke bacteria, morphed into ourselves. LOL!

Some bacterial cells can swim, morph into new forms and even become dangerously virulent

“The tiny RNA molecule, comprised of only two nucleotides, activates a larger RNA structure called a riboswitch. Breaker's lab discovered riboswitches in bacteria six years ago and has since shown that they can regulate a surprising amount of biological activity. Riboswitches, located within single strands of messenger RNA that transmit a copy of DNA’s genetic instructions, can independently “decide’’ which genes in the cell to activate”

Only two nucleotides? That only provides 16 combinations! It will be interesting to see the further levels of regulation that this entails.
