Cell Cycle

Question 1

Cell Cycle

Answer 1

series of events that take place in a cell leading to duplication of its DNA

Question 2

Mitosis

Answer 2

process of dividing the nucleus

Question 3

G0

Answer 3

resting phase; cells no longer divide

Question 4

Trigger Protein

Answer 4

histone

Question 5

Prophase

Answer 5

nuclear membrane is broken down; chromosomes appear; centrioles migrate (only in animal cells)

Question 6

Centrioles

Answer 6

The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division

Question 7

Metaphase

Answer 7

chromosome align; spindle fibers attach to chromosomes

Question 8

Spindle Fibers

Answer 8

divides chromosomes

Question 9

Equatorial Plane

Answer 9

middle of nucleus

Question 10

Anaphase

Answer 10

chromatids move to opposite ends of the cell with the help of spindle fibers

Question 11

Telophase

Answer 11

chromosomes stop moving and the nuclear membrane reforms

Question 12

Cytokinesis

Answer 12

division of the entire cell after the nucleus divides; NOT part of mitosis; differs for plants and animals because plant cells have cell walls

Question 13

Clevage Furrow

Answer 13

indentation of the cell’s surface during the division of the nucleus

Question 14

Cell Plate

Answer 14

The cell plate is a structure that forms in the cells of land plants while they are undergoing cell division

Question 15

Chromosome

Answer 15

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

Question 16

Chromatin

Answer 16

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

Question 17

Chromatid

Answer 17

half of replicated chromosome

Question 18

Centromere

Answer 18

middle of chromosome
