Answers study questions 12 In a simple pathway of bacteria two regulators are working as follows: cell enlargement -->R--> T--> chromosomal replication 1. What is the effect on this system of losing the function of R? T is not active, no chromosomal replication. 2. What is the effect on this system of losing the function of T? Same as above. ********* In a simple pathway of bacteria two regulators are working as follows: cell enlargement -->R--| T--> chromosomal replication 3. What is the effect on this system of losing the function of R? T becomes active and induces chromosomal replication. 4. What is the effect on this system of losing the function of T?

Unformatted text preview: mal replication begins 6. What is the effect on this system of losing the function of T? Same. ****** In a simple pathway of bacteria two regulators are working as follows: cell enlargement -->R--| T--| chromosomal replication 7. What is the effect on this system of losing the function of R? T becomes active and blocks chromosomal replication. 8. What is the effect on this system of losing the function of T? Chromosomal replication begins. ****** 9. In a growing yeast cell CDK has lost the ability to bind cyclin. What should be the effect? It will never become active and cell cycle will be arrested. Lethal consequences. 10. In a growing yeast cell CDK undergoes a change in its function. The kinase activity of this variant is expressed at all times. What should be the effect? The cell will try to undergo S phase at all times. Should be lethal. - 1 -...
