Has anyone ever not needed to pee on ur way to class but as soon as the tardy bell rings u suddenly need to pee And when u ask ur teacher if u can use the restroom they say u should have done it before class? Or is it just me and my bad luck? Bc it happens to me a lot

Okay, biology isn't exactly my strongest subject (it never has been), but i'm pretty sure the answer is nucleotides. dna is made up of nucleotides. each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. there are four different nitrogen bases: adenine (a), thymine (t), guanine (g), and cytosine (c). a always pairs with t, and g always pairs with c.
