Clues

  • a chemical bond formed between two amino acids (7, 4)
  • a protein produced by lymphocytes in response to the presence of the appropriate antigen (8)
  • a type of white blood cell that produces antibodies (1, 10)
  • an antibody produced by a single clone of cells (10, 8)
  • mechanism by which cells engulf particles to form a vesicle or a vacuole (12)
  • process of separating particles of different sizes and densities by spinning them at a high speed in centrifuge (14)
  • the breaking down of large molecules into smaller ones by the addition of water molecules (10)
  • the introduction of a vaccine containing appropriate disease antigens into the body in order to induce artificial immunity (11)
  • the process whereby a chromatid breaks during meiosis and rejoins to the chromatid of its homologous chromosome so that their alleles are exchanged (8, 4)
  • the shrinkage of cytoplasm away from the cell wall that occurs as a plant cell loses water by osmosis (11)
