You perform an experiment where you prevent Cdc20 from binding to APC  in a cell line that usually completes the cell cycle in 60 minutes. Your experiment prevents Cdc20 from binding to APC for 120 minutes, and then you fix and stain the DNA, securin, separase and cohesin proteins. Which of the following would NOT be found in the observed cell?

#I Life Science/ Life Sciences Group – I-V
  1. The cell would contain condensed chromosomes aligned at the metaphase plate.

  2. Cohesins will be localized around the sister chromatids.

  3.  Securin would be bound to separase (appear to co-localize).

  4. The DNA will be decondensed because the cell is in interphase.

Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the liver and testes. For this to happen, there must be direct communication between the extracellular matrix and the developing cells. Which kind of transmembrane protein would most likely be involved in this kind of induction?
