5 Matching questions

  1. Meiosis
  2. Recessive
  3. Sexual reproduction
  4. Polyploid
  5. Gametes
  1. a Eukaryotic organisms or cell with more than two sets of chromosomes.
  2. b Characteristic in which the allele responsible is only expressed in the phenotype if there is no dominant allele present.
  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 Specialised sex cells. In many organisms the gametes are haploid and are produced by meiosis.
  5. e Production of new organisms involving fusion of nuclei from male and female gametes, usually from unrelated individuals. Increases genetic variation in the population.

5 Multiple choice questions

  1. Programmed 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.
  2. 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.
  3. 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. A 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.
  5. A characteristic where both alleles contribute to the phenotype.

5 True/False questions

  1. Neutral mutationCauses 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.

          

  2. Genetic codeAlleles present within cells of an individual, for a particular trait/characteristic.

          

  3. Spindle fibresLarge polymer molecule made of many amino acids joined by peptide bonds.

          

  4. DominantCharacteristic in which the allele responsible is expressed in the phenotype even in those with heterozygous genotypes.

          

  5. Hox clustersSpecific position on a chromosome, occupied by a specific gene.
