  1. Degenerate
  2. Phenotype
  3. Homeobox genes
  4. Programmed cell death
  5. Meiosis
  1. a A term applied to the genetic code that describes the fact that more than one triplet code is used to code for all amino acids other than tryptophan and methionine.
  2. b Genes that control the development of the body plan of an organism.
  3. c Type of nuclear division. A reduction division. The chromosome number is halved. It involves two divisions. It produces cells that are genetically different from each other and from the parent cell.
  4. d Observable characteristics of an organism.
  5. e Alternative term for apoptosis.

5 Multiple choice questions

  1. A reference to the fact that normal body cells can only divide a finite number of times, normally about 50 mitotic divisions. In contrast, tumour cells are essentially immortal.
  2. Eukaryotic cell or organism having only one set of chromosomes. Denoted by n.
  3. The formation of an RNA molecule, using a length of DNA as a template and catalysed by RNA polymerase.
  4. The points where non-sister chromatids within a bivalent join, where they cross over.
  5. Refers to the location of cells with respect to the head end (anterior) or tail end (posterior) of the body.

5 True/False questions

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

          

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

          

  3. GenotypeAlleles present within cells of an individual, for a particular trait/characteristic.

          

  4. ApoptosisType of nuclear division. A reduction division. The chromosome number is halved. It involves two divisions. It produces cells that are genetically different from each other and from the parent cell.

          

  5. Nonsense mutationA change in DNA sequence that introduces a premature stop codon within a DNA coding sequence.
