Cell Division

What is the ultimate goal of a cell during interphase?

• To prepare for cell division

• To increase in size

• To replicate DNA

• To form new daughter cells

Answer explanation

The ultimate goal of a cell during interphase is to prepare for cell division.

What is the function of spindle fibers during mitosis?

• To synthesize DNA

• To help in the movement of chromosomes

• To produce energy for the cell

• To store genetic information

Answer explanation

Spindle fibers aid in the movement of chromosomes during mitosis.

Which stage of mitosis is indicated by the prefix 'meta'?

• Anaphase

• Telophase

• Prophase

• Metaphase

Answer explanation

The stage of mitosis indicated by the prefix 'meta' is Metaphase. During Metaphase, the chromosomes align at the center of the cell before separating into two daughter cells.

What happens in anaphase of mitosis?

• Chromosomes align at the equator of the cell

• Nuclear membrane reappears

• Cytoplasm is divided into two daughter cells

• Sister chromatids separate towards opposite poles

Answer explanation

In anaphase of mitosis, sister chromatids separate towards opposite poles, ensuring proper distribution of genetic material to daughter cells.

What is the main function of cytokinesis in mitosis?

• To divide the cytoplasm and form two daughter cells

• To separate sister chromatids towards opposite poles

• To align chromosomes at the equator of the cell

• To condense chromosomes into X-shaped structures

Answer explanation

The main function of cytokinesis in mitosis is to divide the cytoplasm and form two daughter cells.

What is the purpose of the nuclear membrane becoming less prominent in prophase?

• To produce energy for the cell

• To store genetic information

• To increase the size of the nucleus

• To release the chromosomes

Answer explanation

The nuclear membrane becomes less prominent in prophase to release the chromosomes.

What is the structure that holds together two sister chromatids?

• Centrosome

• Centromere

• Chromatidase

• Centriole

Answer explanation

The structure that holds together two sister chromatids is called the centromere. It is responsible for ensuring proper chromosome segregation during cell division.

What is the main function of the centrioles during mitosis?

• To produce energy for the cell

• To align chromosomes at the equator of the cell

• To assist in the movement of chromosomes

• To separate sister chromatids towards opposite poles

Answer explanation

The main function of the centrioles during mitosis is to assist in the movement of chromosomes.

What is the significance of the prefix 'ana' in anaphase?

• It indicates the first stage of mitosis

• It indicates the middle stage of mitosis

• It indicates the last stage of mitosis

• It indicates the opposite movement of sister chromatids

Answer explanation

The prefix 'ana' in anaphase indicates the opposite movement of sister chromatids.

What is the main function of the spindle fibers during mitosis?

• To divide the cytoplasm and form two daughter cells

• To store genetic information

• To replicate DNA

• To help in the movement of chromosomes

Answer explanation

The main function of the spindle fibers during mitosis is to help in the movement of chromosomes.
