The Genetic code

Cards (9)

  • What are the 3 features of the genetic code?
    Universal
    Degenerate
    Non-overlapping
  • What is meant by Degenerate?
    The same amino acid is coded for by more than one triplet of bases
  • What is meant by universal?
    The same triplet of bases codes for the same amino acid in all organisms
  • What is the advantage of the genetic code being universal?

    It means genetic engineering is possible
  • What is meant by Non-overlapping?

    Each base in a gene is only part of one triplet of bases that codes for one amino acid. Therefore, each codon, or triplet of bases, is read as a discrete unit.
  • What are introns?
    Non-coding sections of DNA that do not code for amino acids and therefore the production of polypeptides.
  • What are Exons?
    Sections of DNA that do code for amino acids and therefore the production of amino acids.
  • What is the genome
    All of the different genes present within a cell
  • What is the proteome?

    The range of proteins a cell is able to produce.
