Mnemonics - (Nov/01/2012 )

I will start this as a universal thread for discussing helpfull teaching menmonics for molecular biology.
I created some for myself, when I was a student, but unfortunatelly they are usually not in english
This is what I have to deal with so far:

The direction of DNA/RNA strand (5' -> 3')
This is one of the first things to deal with, it goes illogically from the higher number to the lower number. I didn't find any real english mnemonic for this, but I kind of translated a czech one.

There is a czech idiom translated like "It goes from ten to five" meaning something is going bad/worse. Since in my student years I got general idea, that everything goes worse, it's only logical that even the DNA goes "from ten to five" in this case from "five to three"

The direction of amino acid strand (N -> C)
The same problem, this time with letters. I think it may be possible to apply the above rule as the C is earlier in the alphabet than N.
But in czech I though of a mnemonic, using czech word KONEC, which means "end". This clearly shows that on the very end of "end" there is C (and also it contains preceding N).
I would be grateful for any ideas about this particular one, I'm going to teach it tomorrow. Some english word with such meaning or maybe something that is used in english schools and I don't know about.
(I've seen the CORN mnemonics for numbering the carbons in amino acid, but that is just oposite of what I need since the direction is reversed)

'N sync?

starts with N, ends with C

Thanks Curtis, but ideal mnemonic would also have some kind of connection to the topic or the thing it's describing, if I could find such, that would be great.
I already told students to think of some, and the best idea will get small unimportant plus for their credit evaluation

what is 'N sync?

wikipedia knows several like these (mostly for beginners):
Dumb Kids Prefer Candy Over Fancy Green Salad (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species)

Idiotic Penguins Make Antarctica Too Cold (Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis)

Harry He Likes Beer Bottle Cold, Not Over Frothy. Nelly's Nanny Might, Although Silly Person, She Climbs Around Kinky Caves; for the first 20 Elements of the Periodic Table. (Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Sodium, Magnesium, Aluminium, Silicon, Phosphorus, Sulphur, Chlorine, Argon, Potassium, Calcium.)

i like that

Perhaps a weird question: but whats the point for learning (just) 20 elements of the periodic table?

I know this is late - but I remember it by amiNo-aCid, N terminus is first, C comes second...

I don't know, but they made us do it in school, perhaps because these are some of the most common elements that people come across, excluding the transition metals like gold, sliver and copper. I think it would be much better if they taught them in the periods, with the reactivities being similar down a column, as the periodic table was designed to do.

Strange, altough, I can imagine they made you do it. But I dont really see the value in it.

No, it's actually quite good! It's connected to the protein and has some kind of inner system too. Thanks!

Oh the Periodic table mnemonics.. our theacher wanted us to know all the elements, according to the groups.

We were making our own ones, very bizzare, translated like "Magda was running through canyon, knocking of banana with her shoulder" (Be, Mg, Ca, Sr, Ba, Ra) and so
