Genetic Code

Genetic Code

1. DNA contains genes; instructions for making proteins

2. Polypeptide chains (proteins) are made from amino acids

3. Different polypeptide chains have different numbers of amino acids

4. A gene is a sequence of bases that codes for the sequence of amino acids in a protein

5. Each amino acid is coded for by a sequence of 3 bases (triplet/codon)

6. The way that DNA codes for proteins is called genetic code

7. Different sequences of bases code for different amino acids

8. The order of mononucleotide bases in a gene determine the order of amino acids in a polypeptide chain
