1
Q

An ordered sequence of events in the life of a cell - from cell birth to cell death

A

Cell cycle

2
Q

A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, metaphase, anaphase, and telophase.

A

Mitosis

3
Q

The first stage of mitosis, in which the
1-chromatin condenses into discrete chromosomes
2- the mitotic spindle begins to form
3- the nucleolus disappears but the nucleus remains intact.

A

Prophase

4
Q

The second stage of mitosis, in which
1- the nuclear envelope fragments
2- the spindle microtubules attach to the kinetichores of the chromosomes.

A

Prometaphase

5
Q

The third stage of mitosis, in which the
1- spindle is complete and
2- the chromosomes are all aligned at the metaphase plate.

A

Metaphase

6
Q

The fourth stage of mitosis, in which the chromatids of each chromosome have separated and the daughter chromosomes are moving to the poles of the cell.

A

Anaphase

7
Q

The fifth and final stage of mitosis, in which daughter nuclei are forming and cytokinesis has begun.

A

Telophase

8
Q

The division of the cytoplasm to form two separate daughter cells immediately after mitosis, meiosis I, or meiosis II.

A

Cytokinesis

9
Q

A cellular structure carrying genetic material, found in the nucleus of eukaryotic cells.

A

Chromosomes

10
Q

The complex of DNA and proteins that makes up eukaryotic chromosomes.

A

Chromatin

11
Q

A haploid reproductive cell, such as an egg or sperm. Gametes unite during sexual reproduction to produce a diploid zygote.

A

Gametes

12
Q

Two copies of a duplicated chromosome attached to each other at the centromere. These are eventually separated during mitosis or meiosis II

A

Sister Chromatids

13
Q

Center where 2 chromatids pinch together.

A

Centromere

14
Q

The phase of the cell cycle that includes mitosis and cytokinesis.

A

Mitotic (M) phase

15
Q

The period in the cell cycle when the cell is not dividing. Chromosomes and organelles are duplicated, and cell size may increase. Often accounts for about 90% of the cell cycle.

A

Interphase

16
Q

Uncontrolled cell growth

A

Cancer

17
Q

A cell containing two sets of chromosomes (2n), one set inherited from each parent.

A

Diploid cell

18
Q

A cell containing only one set of chromosomes (n). (Hint- Sex cells)

A

Haploid cell

19
Q

Growth phase, of the cell cycle, consisting of the portion of interphase before DNA synthesis begins.

A

G1 Phase (Gap1)

20
Q

The phase of the cell cycle; the portion of interphase during which DNA is replicated.

A

S Phase - (Synthesis)

21
Q

Growth phase, of the cell cycle, consisting of the portion of interphase after DNA synthesis occurs.

A

G2 Phase- (Gap2)

22
Q

A new cell wall forms during cytokinesis in the middle of a plant cell

A

Cell plate

23
Q

A nondividing state occupied by cells that have left the cell cycle, sometimes reversibly.

A

G0 Phase

24
Q

Division of the cytoplasm

A

Cytokinesis

25
Q

When Tumor is clustered together

A

Benign

26
Q

When tumor cells have the ability to break away.

A

Malignant

27
Q

When the tumor cells break away from the main tumor and travel around the body.

A

Metastasis
