Which of the following is NOT a checkpoint that controls the progression of the cell cycle?
The G1/S checkpoint determines if conditions are favorable for cell division.
The S/G2 checkpoint checks for DNA damage and determines if all the DNA is replicated.
The metaphase/anaphase checkpoint determines if all chromosomes are attached to the spindle apparatus.
The telophase/cytokinesis checkpoint checks the formation of a cleavage furrow to separate the cells.
Which of the following statements is FALSE concerning sister chromatids?
The formation of sister chromatids doubles the amount of DNA in a cell.
Sister chromatids separate during telophase.
Sister chromatids are held together at the centromere by cohesion proteins.
Sister chromatids are formed during the S phase of the cell cycle.
What does NOT happen in the cytokinesis of plant cells?
Formation of cleavage furrow to separate the cells.
Cell wall forms between the two daughter cells.
The two nuclei are segregated into separate daughter cells.
When the vesicles fuse, their membranes contribute to the formation of plasma membrane on either side of the cell plate.
Sister chromatids separate during
prophase of meiosis I
metaphase of meiosis I
anaphase of meiosis II
anaphase of meiosis I
What is the first stable intermediate of the Calvin Cycle and what enzyme made this intermediate?
3GP, Rubisco
3GP, PEP Carboxylase
3PG, Rubisco
3PG, PEP Carboxylase
Given that the C4 pathway gets around the problems of photorespiration, why don't all plants use it?
It is a more recent process, and many plants have not had time to evolve this pathway.
It also has an energetic cost.
It requires extra enzymes that many plants lack.
It requires special transport tissues that many plants lack.
The Calvin Cycle requires all of the following except
CO2
ATP
NADPH
O2
