How can just four nitrogenous bases--adenine, cytosine, guanine, and uracil--possibly code for all 20 amino acids? Thus, early researchers quickly determined that the smallest combination of As, Cs, ...
There are four bases: Adenine and Guanine (purines); Cytosine and Thymine (Pyrimidines). Purines have two carbon-nitrogen rings while pyrimidines have a single carbon-nitrogen ring. Thus, there are ...
A team of Chinese scientists has uncovered a hidden 3D structure in rice DNA that allows the crop to grow more grain while ...
