Clues

  • 9-triplet microtubule assembly, constantly grow + shrink (10)
  • base of each flagellum or cilium (5, 4)
  • binds tightly to single tubulin molecules + prevents polymerisation, exposure of cell to this prevents spindle formation, taxol has opposite effect (10)
  • communication and transport between all the different areas (12)
  • made of actin (protein), determine + stabilize cell shape, help entire cell/part of cell to move, involved in cytoplasmic streaming + formation of pseudopodia (14)
  • non-pigmented cell in fish scaled, migrate very rapidly in culture, interference w/ actin halts cell migration (4, 13)
  • plasma membrane senses difference, transmembrane signal generated, actin cortex reorganised, centrosome moves to that part of cell, repositions internal membrane system (12)
  • rigid intercellular skeleton, tracks motor proteins can move along, formed from polymerization of tubulin monomers, stabilised by embedding in centrosome. (12)
  • serves as main microtubule organising centre, key role in mitosis (10)
  • use microtubule network as scaffold to position organelles, energy used to move along microtubules or actin filaments (5, 8)
