2. Give an example of a structural protein that DNA codes for:

  • Fibre and Hooves
  • Carbohydrates
  • Collagen and Keratin
  • Haemoglobin and Cellulose

3. What evidence is there to suggest that the genetic code evolved early on?

  • it is non-overlapping
  • it is almost universal
  • it is degenerate
  • it is very long

4. What is mean by the code is non-overlapping?

  • each amino acid is specific to one particular codon
  • each codon is only present in one protein
  • each codon codes for one amino acid
  • only 1 amino acid can be coded for by 1 codon

5. What is meant by the term triplet code?

  • 3 different bases coding for lipids
  • 1 base in a DNA molecule that codes for 3 amino acids
  • a group of 3 bases in a DNA molecule that code for 1 amino acid
  • when DNA has 3 of the same bases in a consecutive order
