Describe this model of DNA
It is perfect
It is wrong because the base pairs are wrong
It is wrong because the proteins are wrong
It is right because the base pairs are correct
What is the significance of the order of nitrogenous bases?
DNA
The order of nitrogenous bases determines the order of amino acids in a protein
The order of nitrogenous bases determines the order of proteins
