Describe the genetic code and its relationship to polypeptides and proteins. (5 points) (PAPER 2 QUESTION BIOLOGY SL)

Sequential answer: 1. What is the genetic code? sets of 3 nucleotides/sets of bases which are called codons (1 point). 2. Which are the bases? bases include adenine, guanine, cytosine and thymine in DNA / adenine (1 point) 3. Link between genetic code and polypeptides? Each codon codes for 1 amino acid (1 point) and each gene codes for a polypeptide (1 point). 4. Process of polypeptide production? Each codon is transcribed into mRNA by base-pair matching/complementary base. (1 point) The Mrna is then transcribed into a sequence of amino acids. (1 point)
