Lesson 2, Chapter 3

Question 1

Mitosis

Answer 1

The process of cell division.

Question 2

Interphase

Answer 2

The phase of the cell cycle where the cell’s DNA molecules are duplicated.

Question 3

Chromosomes

Answer 3

The cell’s DNA molecules after they have condensed during prophase.

Question 4

Dyad

Answer 4

Two identical strands of genetic material that together look like X’s under a microscope.

Question 5

Centromere

Answer 5

The point where dyads are connected.

Question 6

Metaphase

Answer 6

The phase of mitosis where the dyads line up midway between the two sides of the cell.

Question 7

Anaphase

Answer 7

The phase of mitosis where the two strands of the dyads are pulled on by the spindle fibers and separated.

Question 8

Sister chromatids What the two strands of a dyad are called when they separate from each other and move to the oppose ends of the cell.

Answer 8

What the two strands of a dyad are called when they separate from each other and move to the oppose ends of the cell.

Question 9

Telophase

Answer 9

The last phase of mitosis where new nuclear membranes form around each set of DNA molecules.

Question 10

Cytokinesis

Answer 10

A process which occurs during anaphase and telophase; cell organelles are shared between the two daughter cells and a contractile ring contracts, creating two separate cells.
