QCM : Cell Cycle and Division Fundamentals — 6 questions

Question 1

1. If a cell is actively producing gametes during reproduction, which cell type is it most likely to be?

Muscle cell

Somatic cell

Germinal lineage cell

Neuron

Explication

Germinal lineage cells are involved exclusively in gametogenesis, which produces gametes like sperm and ovocytes, making them the most likely cell type to be actively producing gametes during reproduction.

Answer

Germinal lineage cell

Question 2

2. Which statement matches the topic "Phases and events of interphase in the cell cycle"?

Gametes are specialized sexual cells, specifically ovocytes and spermatozoa, produced by germinal lineage cells through gametogenesis

Somatic cells are all body cells capable of division that are neither germinal (sexual) cells nor gametes. They include any cell in the body that can undergo mitosis

Interphase : A phase of the cell cycle that includes G1, S, and G2 phases, during which the cell grows and prepares for division

Germinal lineage cells are the precursor cells that give rise to gametes. They are involved exclusively in gametogenesis, which occurs only in gonads such as ovaries and testicles

Explication

This statement comes directly from the course section dedicated to this topic: Interphase : A phase of the cell cycle that includes G1, S, and G2 phases, during which the cell grows and prepares for division.

Answer

Interphase : A phase of the cell cycle that includes G1, S, and G2 phases, during which the cell grows and prepares for division

Question 3

3. What is the main characteristic of cytokinesis in cell division?

It only occurs in germinal cells during gametogenesis

It results in the formation of two separate daughter cells

It involves the division of the nucleus into four phases

It occurs before nuclear division begins

Explication

Cytokinesis is characterized by the division of the cytoplasm after nuclear division, leading to two separate daughter cells.

Answer

It results in the formation of two separate daughter cells

Question 4

4. What is a key feature of the metaphase/anaphase checkpoint in the cell cycle?

It checks for DNA damage before DNA synthesis

It controls the segregation of chromosomes during cell division

It regulates the exit from mitosis to cytokinesis

It ensures DNA replication is complete before entering mitosis

Explication

The metaphase/anaphase checkpoint controls the segregation of chromosomes during cell division, ensuring proper chromosome distribution.

Answer

It controls the segregation of chromosomes during cell division

Question 5

5. Which statement matches the topic "Comparative features of mitosis and meiosis"?

Somatic cells are all body cells capable of division that are neither germinal (sexual) cells nor gametes. They include any cell in the body that can undergo mitosis

Cellules filles : cellular units produced through division processes that are either genetically identical or diverse, depending on the type of division

Germinal lineage cells are the precursor cells that give rise to gametes. They are involved exclusively in gametogenesis, which occurs only in gonads such as ovaries and testicles

Gametes are specialized sexual cells, specifically ovocytes and spermatozoa, produced by germinal lineage cells through gametogenesis

Explication

This statement comes directly from the course section dedicated to this topic: Cellules filles : cellular units produced through division processes that are either genetically identical or diverse, depending on the type of division.

Answer

Cellules filles : cellular units produced through division processes that are either genetically identical or diverse, depending on the type of division

Question 6

6. What is the main biological role of mitosis as described in the source?

Facilitating genetic recombination during reproduction

Supporting tissue growth and cell renewal

Generating genetic diversity in gametes

Reducing chromosome number in reproductive cells

Explication

Mitosis supports tissue growth, cell renewal, and the maintenance of physiological cell populations by producing two genetically identical and diploid (2n) daughter cells.

Answer

Supporting tissue growth and cell renewal
