5 Matching questions

  1. Segmentation genes
  2. Stutter mutation
  3. Heterozygous
  4. Frameshift mutation
  5. Phagocytosis
  1. a Eukaryotic cell or organism that has two different alleles for a specific gene.
  2. b Genes that control the development of polarity within a body segment during development.
  3. c Causes an expansion or contraction of a run of identical codons within a gene affecting the length of a run of identical amino acids in the polypeptide.
  4. d 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.
  5. e Term to describe the engulfing by macrophages of vesicles from cells that have undergone apoptosis.

5 Multiple choice questions

  1. A change in DNA sequence within a gene that does not lead to a change in the amino acid sequence due to the degeneracy of the genetic code.
  2. Having two sets of chromosomes (eukaryotic cell or organism). Denoted by 2n.
  3. Structure formed on the centromere that attaches the chromosomes to the spindle fibres during mitosis and meiosis.
  4. Genes that control the development of the body plan of an organism.
  5. Failure of members of a homologous pair of chromosomes, or of a pair of chromatids, to separate during nuclear division.

5 True/False questions

  1. PolypeptideLarge polymer molecule made of many amino acids joined by peptide bonds.


  2. GametesA length of DNA that codes for one (or more) polypeptides/proteins. Some may code for RNA or regulate other genes.


  3. transfer RNAA short length of about 100 RNA nucleotides that adopts a clover leaf structure and carries an amino acid to the ribosome to be incorporated into a growing polypeptide chain.


  4. Hox clustersGroups of homeobox genes. More complex organisms have more such groups, probably due to a mutation that duplicated them.


  5. Neutral mutationA mutation that even though it may change a coding sequence exerts no harmful or beneficial effects.
