Homework Answers
A.
Stage 1- G1 phase
Stage 2 - S phase
Stage 3 - G2 phase
Stage 4 - mitosis
Stage 5 - cytokinesis.
B.
Each chromosome is duplicated - S phase
Cell divides in to two daughter cells - cytokinesis
Cell contents, except for chromosomes, are duplicated - G1 phase
Chromatids are separated from each other forming two identical nuclei - mitosis
The majority of cell's life, when it is not actively engaged in chromosomal or cellular division - interphase
The cell double - checks duplicated chromosomes and makes any needed repairs - G2 phase.
C.
Chromosomes line up along the cell's equitorial plate - metaphase
Chromosomes, now real chromosomes, move to opposite side of the cell - anaphase
Chromosomes shorten and thicken - prophase
Nuclear Membrane forms - telophase
Spindle fibres attach to kinetochores on chromosomes and begen to pull - prometaphase
D.
The number of chromosomes in the cell doubles - anaphase
The nuclear Membrane breaks down - prometaphase
The spindle begins to form - prophase
Chromosomes decondense - telophase
Chromosomes are in a line down the center of the cell - metaphase
E.
G1 phase - 46
G2 phase - 46
S phase - 46
Prophase - 46
Prometphase - 46
Metaphase - 46
Anaphase - 92
Telophase - 92

Match the stage of mitosis with the correct description.
Match the stage of mitosis with the correct description.a. Microtubles that are attached to each chromosome shorten, pulling the sister chromatids apart.b. The chromosomes line up single file in the middle of the cell. Sister chromatids are clearly visible in this stage.c. The chromosomes that were pulled apart reach their respective poles. The chromosomes decondense. The nuclear envelope re-forms. The cytoplasm with organelles divides.d. Chromosomes have replicated and appear as an "X". The nuclear envelope begins to break down. The...
