Four bases hence four nucleotides arranged on a polynucleotide strand making up a DNA strand.
This “alphabet” arrangement is responsible for carrying the genetic code.TRIPLET CODON
4 polynucleotide strand making up a DNA strand. 1 = 4
4 amino acids would make up the polypeptide chain.2 = 16
Obviously a code composed of three bases could incorporate all 20 amino acids into the structure of protein molecules.
Such a code would produce ________ combinations of bases.
43 = 64
Let’s look at themTRIPLET CODON
DNA makes RNA and RNA makes PROTEIN which is responsible for how we look and function
