5 Matching questions

  1. Genome
  2. Stop codon
  3. Gametes
  4. Insertion/deletion mutation
  5. Operon
  1. a All the genetic information within an organism/cell.
  2. b A stretch of DNA consisting of two or more genes that are transcribed together and coregulated.
  3. c Specialised sex cells. In many organisms the gametes are haploid and are produced by meiosis.
  4. d A change in DNA sequence involving the introduction or loss of 1- 1000s of bases.
  5. e One of three triplet codes (UGA, UAG or UAA) that causes the termination of translation by the ribosome.

5 Multiple choice questions

  1. 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. Genes that control the development of the body plan of an organism.
  3. The fundamental relationship between DNA, RNA and protein first outlined by Francis Crick in 1958.
  4. Molecule (nucleotide derivative) found in all living cells and involved in energy transfer. When it is hydrolysed energy is released.
  5. A characteristic where both alleles contribute to the phenotype.

5 True/False questions

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

          

  2. TranscriptionThe formation of an RNA molecule, using a length of DNA as a template and catalysed by RNA polymerase.

          

  3. DNA mutationA change to the DNA structure altering the sequence of bases.

          

  4. RecessiveCharacteristic in which the allele responsible is only expressed in the phenotype if there is no dominant allele present.

          

  5. Coding strandA characteristic where both alleles contribute to the phenotype.
