Cell Cycle

Question 0

Stages of Mitosis

Answer 0

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

Question 1

Four Phases of Cell Cycle

-What is it?

Answer 1

Cell grows, prepares for division, and divides

• G1: 10 hours
• S: 9 hours
• G2: 4 hours
• M: 1 hour

Question 2

Interphase

-3 stages?

Answer 2

1. G1: cell growth
2. S phase: DNA replication
3. G2: preparation for mitosis

Question 3

Spindle

Answer 3

Web structure made up of micro tubule fibers, arranged chromosomes on correct positions for cell division

Question 4

Prophase

Answer 4

Chromatin in nucleus condenses to form pair of chromosomes. Nucleolus begins to break down. Centrioles move to opposite ends of nucleus. Nuclear membrane breaks down.

Question 5

Metaphase

Answer 5

Spindle becomes fully developed and chromatid pairs place themselves in individual fibers and align along center of spindle. Nuclear membrane gone.

Question 6

Anaphase

Answer 6

Chromatid pairs splits into two. Pairs travel to opposite end of spindle. The halved chromatids clef chromosomes

Question 7

Telophase

Answer 7

Two new nuclei formed when chromosomes reach the opposite poles of cell. Nuclear membrane formed and nucleolus reappears. Chromosomes disperse in nucleus

Question 8

Cytokinesis

Answer 8

Division of cytoplasm. Cytokinesis begins during anaphase

Question 9

• Cell contains ____ of ___ chromosomes

- Reproductive cells only have ___ of chromosomes

Answer 9

Two sets

23
