What is the correct order of the stages of mitosis?

1-Metaphase 2-Telophase 3-Anaphase 4-Prophase

• 4,1,2,3

• 2,3,1,4

• 1,2,3,4

• 4,1,3,2

During which stage of mitosis does the nuclear envelope begin to disappear?

• Metaphase

• Telophase

• Interphase

• Prophase

• Anaphase

During which stage of meiosis do the sister chromatids begin to move toward the poles?

• Prophase I

• Metaphase 1

• Anaphase 1

• Telophase 1

• Anaphase II

What type of checkpoint dictates whether the cell will continuously divide or stop, and also checks the cell size, presence of growth factors, and DNA damage?

• G1 checkpoint

• S checkpoint

• G2 checkpoint

• M checkpoint

Which checkpoint occurs at metaphase stage of mitosis. It is regulated by Anaphase-promoting complex (APC). It checks whether all chromosomes are properly attached to the spindle fibers and its alignment at the metaphase plate.

What is the longest phase of the cell cycle process. It is also the known as the resting phase before entering into mitosis proper

In eukaryotic cells, there are three major checkpoints that control the cell cycle process. Choose the 3 major checkpoints

• G1 checkpoint at the G1/S transition

• G2 checkpoint at the G2/M transition

• Spindle checkpoint, the transition from metaphase and anaphase

• G0 checkpoint, the transition from metaphase and anaphase

before the cell divides it spends most of its life in the period of cell growth called Interphase with three sub-stages:

What are the 3 substages of Interphase

Choose 2 criteria that G2 checkpoint checks

• DNA integrity (Is any part of the DNA damaged?)

• DNA replication (Is the DNA replication completed in the S phase?)

• Cell’s size (Does the cell large increase its size or large enough for cell division?)

• Nutrients (Does the cell have enough reserve energy and nutrients for cell division?)

What is the order of interphase

• G1, S phase, G2

• G1, G2, S phase

• S phase, G1, G2

• G2, S phase, G1
