Question

what does it mean when scientist say that living organisms share a universal genetic code

Answer 1

it means that all living organisms have a shared ancestor deep in the past, so all living organisms are related to some degree. We might share 99.8% DNA with chimps, but we also share maybe (just a guess, I don't remember the exact number) 24% DNA with lettuce. If all living organisms are related, than their genetic code is universal - one and the same for all organisms.

Answer 2

DNA reminds me of Banana :P
