General Biology 1 (Part III)

Question 1

The sequence of stages from one division to the next.

Answer 1

Cell Cycle

Question 2

It is an orderly progression of events that occur between the time a new cell has arisen from the division of the parent cell to the point when two daughter cells are produced

Answer 2

Cell Cycle

Answer 5

G1 Phase
S Phase
G2 Phase

Question 6

The cell’s primary growth phase.

Answer 6

G1 Phase

Question 7

The cell copies its DNA to produce two sister chromatids and replicates its nucleosomes.

Answer 7

S Phase

Question 8

Involves further cell growth and organization of cellular contents.

Answer 8

G2 Phase

Question 9

The Period when chromosome divide.

Answer 9

Mitosis

Question 10

What are the 4 stages of Mitosis?

Answer 10

Prophase
Metaphase
Anaphase
Telophase

Question 11

During this phase, chromosome appear as long thin intertwined threads but, as this stage continues, the chromosome becomes shorter and thinner.

Answer 11

Prophase

Question 12

Stars when the chromosome with spindle fibers attached has moved to the equator of the cell.

Answer 12

Metaphase

Question 13

The centromeres divide, converting each sister chromatid into a chromosome.

Answer 13

Anaphase

Question 14

The chromosomes have reached the opposite ends of the cell.

Answer 14

Telophase

Question 15

Takes place toward the end of Mitosis.

Answer 15

Cytokinesis

Question 16

Formation of a constriction called cleavage furrow at the equator of the cell.

Answer 16

Animal Cytokinesis

Question 17

The dividing cell forms a similar structure called the cell plate.

Answer 17

Plant Cytokinesis

Question 18

The ___________ has key checkpoints where feedback from the cell about its condition every checkpoint.

Answer 18

Cell Cycle

Question 19

What are the 3 Principle Checkpoints where feedback from the cell about its condition every checkpoint:

Answer 19

G1 Checkpoint
G2 Checkpoint
M PHASE

Question 20

What happen to the G1 Checkpoint?

Answer 20

When cell growth is assessed.

Question 21

What happen to G2 Checkpoint?

Answer 21

When DNA replication is assessed

Question 22

What happen to M Checkpoint

Answer 22

ensures that the chromosomes are properly attached to the spindle and will be distributed accurately

Question 23

What is the Purpose of Mitosis?

Answer 23

To keep the number of chromosomes constant in all of the cell of the body, so that every cell contains identical genetic material.

Question 24

What is the Purpose of Meiosis

Answer 24

To provide variation in gametes and to keep the number of chromosomes constant generation after generation.

Question 25

What is the 2 Consecutive Nuclear Divisions

Answer 25

Meiosis I Meiosis II

Question 26

What happened at the Interphase of Meiosis

Answer 26

S phase: Chromosomes are duplicated. The resulting sister chromatids are held together in the centromere. The centrosomes are also duplicated.

Question 27

What will happen at Meiosis I, Prophase 1?

Answer 27

the homologous chromosomes pair and form synapsis. The paired chromosomes are bivalent. Crossing over occurs.

Question 28

What will happen at Meiosis I, Metaphase 1

Answer 28

Bivalents align.

Question 29

What will happen at Meiosis I, Anaphase 1

Answer 29

the homologous chromosomes separate.

Question 30

What will happen at Meiosis I, Telophase 1

Answer 30

nuclear envelopes reforms forming two daughter cells.

Question 31

What will happen at Meiosis II, Prophase II?

Answer 31

chromosomes condenses and new set of spindle fibers forms.

Question 32

What will happen at Meiosis II, Metaphase II?

Answer 32

chromosomes align themselves along the metaphase plate with the help of spindle fibers.

Question 33

What will happen at Meiosis II, Anaphase II?

Answer 33

the chromatids are pulled apart by the spindle fibers.

Question 34

What will happen at Meiosis II, Telophase II?

Answer 34

the cell divide forming 4 haploid cells.

Question 35

How many cells are there in the (Meiosis) Haploid?

Answer 35

23

Question 36

How many cells are there in the (Mitosis) Diploid?

Answer 36

46

Question 37

Answer 37

Apoptosis

Question 38

A cell that leaves the Cell Cycle

Answer 38

G0

Question 39

Does not divide into 2 daughter cells

Answer 39

Neurons

Question 40

How many chromosomes are in Mitosis?

Answer 40

46

How many chromosomes are in Meiosis?

Answer 41

23
