  1. Allele
  2. Genetic variation
  3. Polyploid
  4. Monogenic
  5. DNA mutation
  1. a An alternative version of a gene carrying sequence differences.
  2. b A change to the DNA structure altering the sequence of bases.
  3. c Variation of genetic information in a gene pool.
  4. d Characteristic coded for by one gene.
  5. e Eukaryotic organisms or cell with more than two sets of chromosomes.

5 Multiple choice questions

  1. Alternative term for apoptosis.
  2. A change in the DNA within a gene involving the insertion or deletion of a number of bases that is not a multiple of three. This causes the downstream gene sequence to be scrambled because the correct reading frame is lost.
  3. Failure of members of a homologous pair of chromosomes, or of a pair of chromatids, to separate during nuclear division.
  4. A stretch of DNA consisting of two or more genes that are transcribed together and coregulated.
  5. Alleles present within cells of an individual, for a particular trait/characteristic.

5 True/False questions

  1. HomozygousEukaryotic cell or organism that has two different alleles for a specific gene.


  2. GenomeAll the genetic information within an organism/cell.


  3. MutationStructural change to genetic material - either to a gene or to a chromosome.


  4. PhagocytosisProgrammed cell death. An orderly process by which cells self-destruct in an orderly fashion after a certain number of cell divisions, or if they cannot repair DNA damage.


  5. ATPSmall vesicle formed that breaks away from the cell membrane during apoptosis
