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

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

3. What is meant by the code is degenerate?

  • only one codon can code for one amino acid
  • a given amino acid maybe coded for by more than one codon
  • all amino acids have at least 5 different codons
  • 1 amino acid can only be coded for by one specific codon

4. What is meant by the term gene?

  • a short strand of DNA
  • a section of DNA
  • A sequence of DNA nucleotides that code for a polypeptide
  • a section of DNA that codes for lipids

5. What is meant by the term triplet code?

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