Witchcraft (seriously, what did you use? I might have to use the same for my graphics lab at school).
Clorox spray, lots of paper towels, and 15 minutes of good ol scrubbing
My finger still hurts
kazhloar asked "Waitaminute: I learnt basic science with mitose/meïose gamètes DNa ARN (RNA?) (it's late, I used the French words, sorry) but what is it about "quarduplexes" or "some form z shapes"? Inquiring minds want to know. (if that's not too much to ask, obviously. Please?)"
Oh yeah sure!
So we’re all familiar with the Watson and Crick model of DNA:
But that’s not the only structure DNA can take. It’s the structure that the majority of DNA are in, but they can also be in these other structures: Z-DNA, A-DNA, B-DNA, and C-DNA:
These structures form in the presence of certain ions or other conditions.
DNA can also form these crazy things called G-quadruplexes (aka G-tetrads). They’re DNA rich in Guanine so are able to form this structure:
And then depending on how many DNA strands there are, it can be tetrameric (4 strands), dimeric (2 strands), or monomeric (1 strand, as in the figure above).
Mind-blowing, huh? And I’m sure this is probably the 1st time a lot of you have heard of DNA being structured differently, because I definitely didn’t learn this until I took a graduate level Genetics course for fun a year ago.
