Question 1

Chromosome

Answer 1

Threadlike structure within the nucleus that contains genetic information that is passed on from one generation to the next.

Question 2

Chromatin

Answer 2

Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones.

Question 3

Cell cycle

Answer 3

In which a cell grows, prepares for division, and divides to form two daughter cells.

Question 4

Interphase

Answer 4

Period of the cell cycle between cell divisions in which the cell grows.

Question 5

Mitosis

Answer 5

Part of eukaryotic cell division during which of the cell nucleus divides.

Question 6

Cytokinesis

Answer 6

Division of a cytoplasm to form two separate daughter cells.

Question 7

Prophase

Answer 7

Longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible.

Question 8

Chromatid

Answer 8

One of two identical “sister” parts of a duplicated chromosome.

Question 9

Centromere

Answer 9

Reigion of a chromosome where the two sister chromatids attach.

Question 10

Centriole

Answer 10

Structure in an animal cell that helps to organize cell division.

Question 11

Metaphase

Answer 11

Phase of mitosis in which the chromosomes lineup across the center at the cell.

Question 12

Anaphase

Answer 12

Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell.

Question 13

Telophase

Answer 13

Phase of mitosis in which the distinct individual chromosomes we begin to spread out into a tangle of chromatin.
