Need To Be Silly Sometimes

I was in class during Higher Biology looking at the structures of Dna..And looking at the bases/ nucleotides,.., Adenine, Guanine, Cytosine, and Thymine,...And how they code for a codon on a wheel diagram....My lecturer, I noticed she was wearing a green jumper...She made an example when selecting nucleotides listed A,G,C,T...She said "lets take "C" for example...she then selected C again...and a third time C...I was thinking "Celtic"...But when we went onto the structure of Transfer RNA (Ribonucleic Acid)...She said "The structure looks like a beautiful four leaf clover!".....Green Jumper, selected C only.When there was 4 nucleotides to choose from....said a four leaf clover structure is beautiful!!....She's definitely Celtic!!! 🍀🍀🤣🤣🤣🤣
