Dna

• what is a purine

  A + G , they are 2 ringed
• what is a pyramidine

  T + C, 1 ringed
• A-T has 2 hydrogen bonds
• C-G has 3 hydrogen bonds
• 2 nucleotide strands are anti parallel
• A triplet code is when three bases is known as a codon which codes for one specific amino acid
• A non-overlapping genetic code is each base in a sequence is read once
• Degenerate genetic code is that more than one triplet can code for a particular amino acid
• Gene

  A sequence of bases on a dna that codes for a sequence of amino acids in a polypeptide
