The genetic code uses three bases to encode one amino acid. Why can't the code use only two bases to encode each amino acid?
If a bacterial protein is 3,300 amino acids long, how many nucleotidepairs long is the gene sequence that codes for it?
If you know the sequence of amino acids in a protein, what does the genetic code table allow you to infer about the sequence of base pairs in the gene that specifies that protein?
