Purine and pyrimidine nucleotides mnemonic

Mnemonic for purine nucleotides:
"Pure as gold"
"PURe as AG"
Purine nucleotides are Adenine and Guanine.

"Goooold"












Mnemonic for pyrimidine nucleotides:
"Cut the pie"
"CUT the PY"
Pyrimidine nucleotides are Cytosine, Uracil and Thymine.

"3.14159265..."










How to remember that it is pyrimidine - pyrimidine dimers and not purine - purine dimers that are formed on exposure to UV light: Pyrimidine is the bigger word. People who have big hearts fall in love with each other.

"It's bigger on the inside."

  1. another nice one ^-^
    P.S (yet again! XD) mnemonic to easily tell apart purine and pyrimidine from a given structure [only purine from pyrimidine, not cytosine from uracil or adenine from guanine]:-
    pyrimidine:- long name, short structure (1 ring)
    purine: short name, long structure (2 rings)

      I had made some really nice mnemonics on how to remember the structures (I actually drew the purine and pyrimidine structures in my B'chem paper getting an 80+ in my exam, that's how a nerdy I was in my first year xD)
      I'll let you know when I upload em <3
