Quiz zum Vortrag
Which of the following occurs in allosteric control of ribonucleotide reductase?
- The binding of dGTP at the allosteric site favors the binding of ADP at the active site.
- The binding of dATP at the active site activates the enzyme.
- The binding of dTTP at the allosteric site favors the binding of UDP at the active site.
- The binding of dGTP at the allosteric site favors the binding of UDP at the active site.
- There is no relationship between the binding of dGTP and ADP.
An abundance of the dATP in the cell leads to what?
- The deactivation of ribonucleotide reductase.
- The activation of ribonucleotide reductase.
- The generation of ATP molecules via the activity of ribonucleotide reductase.
- The generation of dAMP molecules via the activity of ribonucleotide reductase.
- The generation of dGTP molecules via the activity of ribonucleotide reductase.
Which reaction does the enzyme dUTPase catalyze, and for what purpose is this reaction necessary?
- It catalyzes the reaction from dUTP to dUMP; this is necessary to prevent its utilization via the DNA pol enzyme.
- It catalyzes the reaction from dUMP to dUTP; this reaction makes it available for the DNA pol enzyme during replication.
- It catalyzes the reaction from dUMP to dTMP; this reaction is needed to make it available for the DNA pol enzyme during replication.
- It catalyzes the reaction from dTMP to dUMP; this needs to be available for the DNA pol enzyme during replication.
- It catalyzes the reaction from dUTP to dTTP; this is required for the DNA pol enzyme during replication.
