Stuff on DNA

I usually remember these by the fact that the letters  "CG" is *curvy* like the number 3 and AT are the other number: 2.

If anyones watched GATTACA, I just thought the AT go together and presto!

*likes*

My method was G and C are 3.

[m@tty]

C is the third letter of the alphabet...

Nah, I just remember... somehow... read it a few times, then remembered.

[iffets12345]

i think i might have that disease where i can see words with letters and like, numbers with colours, cause G and C just feel like a 3 to me

You may be like me? Do you see colors and taste music? When you do math in your head do you like *see* an answer without thinking?

Its called synesthesia i think.

Just for anyone who doesn't do Biology and want's a super schmik way to remember what the purine and pyramidine bases are....

Just remember that you CUT yourself on a glass pyramid

C - cytosine
U - uracil
T - thymine

The rest are then obviously purine.

LOL. Even though Ive commited that to memory, I absolutely LOVE that!

CUT - Pyramid

[shinny]

I used the trick where all the ones with 'y's in them go together. pYramidine, thYmine and cYtosine. And uracil would be equivalent to whatever thymine is I guess.

[m@tty]

I just think that the shorter name (purine) is for the bigger bases (A and G).

Yes, synesthesia I think, your symptoms are kind of similar but not the taste part. I see answers and things in my mind. Things have "feels" to them, like words and colours and numbers. weird

Okay, thought I'd upload this.  It is just the bases from the data book, but I put the polar charges on them just in case we have to draw the hydrogen-bonding between two base pairs.

I think this is right, if not, my teacher really needs to get her shit together.

Anyway just remember, start from the top, and work your way left.  A and T have two polar sites, whilst C and G have 3.  Any group with H in it is always +, whilst O and N on their own are -

Hope this helps, because I was really struggling to match up the molecules but with this it seems a lot easier.

Yeah I did the same thing, CUT mnenomic also is rad... my teacher introduced FON for hydrogen bonding and OIL RIG CAT for redox ...

[olly_s15]

for redox my chem teacher suggested that you place "any verb you like" in this sentance

the red cat ____ an ox

"red" meaning reduction at "cat" meaning cathode and "ox" meaning oxidation at "an" meaning anode

obviously we came up with some interesting ways to remember it

[stonecold]

So for FHONCl and FO2, that would mean oxygen would have an oxidation number of +0.5 ?

Also, isn't nitrogen totally dependent on the formula.

i.e.  NO3-  Nitrogen is +5
      NH4+  Nitrogen is -3

[stonecold]

Although if you were to get something where N was the highest priority, then I guess it would be at -3 state, as it is in group 15 of the periodic table.

All of the other charges just come from the group number lol...
