Q3 Test: DNA, CELL CYCLE AND MITOSIS

What is this phase of mitosis?

• Prophase

• Anaphase

• Cytokinesis

• Telophase

What is this phase in Mitosis ?

• Metaphase

• Telephase

• Prophase

• Anaphase

Interphase is divided into three phases , Which are ?

• G1

  S

  G2

• Mitosis

  G1

  G2

• S

  G2

  Cytokiesis

Which of the following are the three major stages of the cell cycle IN CORRECT ORDER ?

• Mitosis or M-phase, Cytokinesis, Interphase

• Interphase, Cytokinesis, M-phase

• Interphase, M-phase, Cytokinesis

Which of the following is NOT true about mitosis?

• The chromosome number in the resulting cells is the same as parent cell's chromosome number

• The number of chromosomes of the daughter cells is one-half of the parent cell's chromosomes.

• Mitosis is also a mode of asexual reproduction

• DNA replication is completed prior to mitosis during the S- phase.

What is the longest stage of the cell cycle?

• Interphase

• Mitosis

• Cytokineses

The cell cycle is described as ?

• a period during which the cell undergoes growth

• an ordered series of events that leads to cell growth and division into two daughter cells

• the DNA replication.

• division preparation and organelles are duplicated

In the cell cycle diagram, when does DNA make exact copy of itself?

• Mitosis ( M-phase)

• Synthesis or S-phase

• G2

What does phase C represent in the diagram?

• Mitosis

• G2

• G1

What is the function of Phase B?

• the chromosomes enter a relaxed state that allows the enzyme DNA polymerase to access the DNA double helix inside each chromosome.

• extra protein is often synthesized, and the organelles multiply until there are enough for two cells.

• the cell synthesizes various enzymes and nutrients that are needed later on for DNA replication and cell division.
