If they’re doing it to kill themselves, they die, man.
There are 4 nucleotides. Guanine (G), Cytosine (C), Thymine (G) and Adenine (A).
C and T are called pyrimidines, and are longer than G and A.
G and C connect using 3 hydrogen bonds, but A and T bond using only 2.
1. The ETC (electron transport chain) produces most ATP so C
2. I'm not exactly sure, but whenever there is less oxygen, fermentation takes place. I'd go for A,but you might want to check ur lessons or something.
