Cell Division

Question 1

What is a chromosme?

Answer 1

A gene-carrying structure found in the nucleus. Each chromosome has one very long DNA molecule and associated proteins.

Question 2

What is a haploid?

Answer 2

Organism/Cell with one set of chromosomes.

Question 3

What is a diploid?

Answer 3

Organism/Cell with two sets of chromosomes.

Question 4

What is a karyotype?

Answer 4

Chromosome pairs of a cell arranged by size + shape used to identify sex + genetic abnormalities.

Question 5

What is the order of the cycle?

Answer 5

Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis.

Question 6

What is interphase?

Answer 6

the longest period of the cell cycle between cell divisions

Question 7

What is cancer?

Answer 7

Disease where cell growth + division isn’t maintained by proteins so cells grow + divide uncontrollably

Question 8

What is a chromatid?

Answer 8

An identical sister part of a duplicated chromosome

Question 9

What is mitosis?

Answer 9

during eukaryotic cell division the nucleus divides

Question 10

What is G1?

Answer 10

Cell growth

Question 11

What is S Phase (Synthesis)?

Answer 11

DNA is copied

Question 12

What is G2?

Answer 12

Final preparation phase. Cell checks for DNA errors and prepares for Mitosis

Question 13

What is cytokinesis?

Answer 13

Division of the cytoplasm during cell division

Question 14

What is prophase?

Answer 14

Chromosomes become visable, nuclear envelop dissolves, spindle forms

Question 15

What is metaphase?

Answer 15

Chromosomes line up in the middle of the cell

Question 16

What is anaphase

Answer 16

Phase of mitosis: chromosomes separate and move to opposite ends of the cell

Question 17

What is telophase?

Answer 17

Final phase of cell division, chromosomes move to opposite ends of the cell and two nuclei are formed.

Question 18

Centromere

Answer 18

Area where the chromatids of a chromosome are attached. (MIDDLE DOT)

Question 19

What are spindle fibers/microtubules?

Answer 19

Protein structures which move the chromosomes during cell division.

Question 21

What phase do chromosomes align in the middle?

Answer 21

Metaphase

Question 22

What phase are the chromosomes pulled apart?

Answer 22

Anaphase

Question 23

What phase do two nuclei form? (1 cell)

Answer 23

Telophase

Question 24

When does the cell split into two new cells?

Answer 24

Cytokinesis
