Describe how Cdc14 triggers the exit from mitosis in the budding yeast, S. cerevisiae.

#I Life Science/ Life Sciences Group – I-V

  1. Cdc14 is a protein phosphatase, which at anaphase is activated by the mitotic exit network. Once activated, Cdc14 dephosphorylates APC/CCdh1 and Sic1, which promotes mitotic cyclin degradation and mitotic CDK inactivation, respectively.

  2. Cdc14 is a protein kinase, which at anaphase is activated by the mitotic exit network.  Once activated, Cdc14 phosphorylates APC/CCdh1 and Sic1, which promotes mitotic cyclin degradation and mitotic CDK inactivation, respectively.

  3. Cdc14 is a protein phosphatase, which at anaphase is activated by the mitotic exit network.  Once activated, Cdc14 dephosphorylates APC/CCdc20 and Sic1, which promotes mitotic cyclin degradation and mitotic CDK inactivation, respectively.

  4. Cdc14 is a protein phosphatase, which at metaphase is activated by the mitotic exit network.  Once activated, Cdc14 dephosphorylates APC/CCdh1, which promotes mitotic cyclin degradation and mitotic CDK inactivation.

An industrial waste-water stream is fed to a stirred-tank reactor continuously and the cells are recycled back to the reactor from the bottom of the sedimentation tank placed after the reactor. The following are given for the system: F = 100 l/h; S0 = 5000 mg/l; mm = 0.25 h-1 ; Ks = 200 mg/l; α (recycle ratio) = 0.6; C (cell concentration factor) = 2; Y M X/S = 0.4. The effluent concentration is desired to be 100 mg/l.  Determine the required reactor volume.

With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 
You do each PCR reaction on chromosome 15 and load each one into a separate well of an agarose gel, and then run the gel.
 

 which number of repeats did Baby C inherit from his mother?
