What are the stages of mitosis?

• telophase, anaphase, metaphase, prophase

• prophase, metaphase, anaphase, telophase

• interphase, prophase, metaphase, anaphase

• prophase, metaphase, telophase, anaphase

Describe the cell division process.

• Cell division is the process by which a parent cell divides into two or more daughter cells.

• Cell division is the process by which a parent cell divides into three or more daughter cells.

• Cell division is the process by which a parent cell combines with another cell to form a daughter cell.

• Cell division is the process by which a parent cell divides into two or more parent cells.

What is the role of spindle fibers in mitosis?

• Spindle fibers help to hold the chromosomes together during mitosis.

• Spindle fibers are responsible for the synthesis of new DNA during mitosis.

• Spindle fibers play no role in mitosis.

• Spindle fibers separate the chromosomes during mitosis.

What are motor proteins and how are they attached to the centromere of chromosomes?

• Motor proteins are attached to the centromere of chromosomes through DNA.

• Motor proteins are not attached to the centromere of chromosomes.

• Motor proteins are attached to the centromere of chromosomes through ribosomes.

• Motor proteins are attached to the centromere of chromosomes through microtubules.

Explain the difference between chromatin and chromatids.

• Chromatin is the two identical copies of a chromosome that are joined together by a centromere, while chromatids are the complex of DNA and proteins that make up the chromosomes.

• Chromatin and chromatids are two different terms for the same thing.

• Chromatin is the condensed form of DNA that is visible during cell division, while chromatids are the loose form of DNA that is visible during interphase.

• Chromatin is the complex of DNA and proteins that make up the chromosomes, while chromatids are the two identical copies of a chromosome that are joined together by a centromere.

What are centrioles and centrosomes and what is their role in mitosis?

• Centrioles are large spherical structures found in plant cells that play a role in cell division.

• Centrosomes are the main energy-producing organelles in animal cells.

• They help in the synthesis of proteins during mitosis.

• Centrioles are small cylindrical structures found in animal cells that play a role in cell division. Centrosomes are the main microtubule organizing centers in animal cells and contain a pair of centrioles. They help in the organization and separation of chromosomes during mitosis.

Define chromosomes and their function in cell division.

• Chromosomes are only present in the nucleus of the cell and do not play a role in cell division.

• Chromosomes are responsible for producing energy in the cell during division.

• Chromosomes are only found in animal cells and have no function in cell division.

• Chromosomes are responsible for carrying genetic information and facilitating cell division.

What is cleavage and how does it contribute to cell division?

• Cleavage is the process of cell death and it contributes to cell division by eliminating excess cells.

• Cleavage is the process of cell division and it contributes to cell division by ensuring equal distribution of genetic material and cytoplasm between daughter cells.

• Cleavage is the process of cell fusion and it contributes to cell division by creating larger cells.

• Cleavage is the process of cell differentiation and it contributes to cell division by creating specialized cells.

Which stage of mitosis involves the separation of sister chromatids?

• metaphase

• telophase

• anaphase

• prophase

What happens to the nuclear envelope during mitosis?

• The nuclear envelope breaks down and disappears.

• The nuclear envelope becomes thicker and more prominent.

• The nuclear envelope remains intact and unchanged.

• The nuclear envelope shrinks in size but remains visible.
