Mitosis Review - Science

Question 1

Mitosis

Answer 1

The division of the contents of the nucleus
(Prophase, Metaphase, Anaphase, Telophase are the 4 phases of mitosis)

Question 2

Cytokinesis

Answer 2

The division of the rest of the cell such as cytoplasm, organelles, and cell membrane
- Two new cells, one around each new daughter cell
- Comes after Telophase

Question 3

What does each cell division produce

Answer 3

Two genetically identical cells called daughter cells

Question 4

Prophase

Answer 4

• Chromatin condenses into Chromosomes
• Nucleolus and Nuclear membrane dissolve
• Centrioles separate and move to opposite ends (poles)
• Spindle fibres form at the centriole (asters) and stretch across the cell (polar)
• Spindle fibres attach to one side of each centromere (kinetochores)

Question 5

Metaphase

Answer 5

• Double-stranded chromosomes line up along the middle of the cell (The metaphase or equatorial plate)

Question 6

Anaphase

Answer 6

• Spindle fibres being to shorten and contract
• Centromeres are separated
• Each chromosome splits into two sister chromatids
• The two sister chromatids move to opposite ends (poles) of the cell
• If successful, each daughter cell will have a complete set of genetic information

Question 7

Telophase

Answer 7

• Spindle fibres disappear
• Nuclear membrane form around each set of chromosomes
• Nucleolus appears within each nucleus
• Single-stranded chromosomes start to condense into thin strands of chromatin
• Cleavage furrow forms in animal cells
• The cell plate begins to form in plant cells

Question 8

Chromatin

Answer 8

the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA.

Question 9

Chromatids

Answer 9

One of the two identical halves of a chromosome that has been replicated in preparation for cell division

Question 10

Centromeres

Answer 10

The region of a chromosome to which the microtubules of the spindle attach via the kinetochore during cell division.

Question 11

Spindle Fibres

Answer 11

a network of fibers that are formed during the cell division process.

Question 11

Chromosomes

Answer 11

A threadlike structure of nucleic acids and proteins found in the nucleus of most living cells, carrying genetic information in the form of genes.
