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 ...

Information in DNA is stored as code sequences made up of nitrogenous bases. Each cell has the same sequence of codes but executes a different function.

The complementary base pairing in DNA leads to a specific ratio of nucleobases, known as Chargaff's rule. According to this rule, the amount of adenine is equal to the amount of thymine, and the ...
