Cell Cycle and Mitosis Concepts

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase and the mitotic phase.

Front

What are the main stages of mitosis?

Back

The main stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What role do spindle fibers play in mitosis?

Back

Spindle fibers are responsible for pulling daughter chromosomes apart during cell division.

Front

What is a nucleotide composed of?

Back

A nucleotide is composed of a phosphate group, a sugar molecule, and a nitrogenous base.

Front

What is the function of centrioles during cell division?

Back

Centrioles help organize the spindle fibers that separate chromosomes during mitosis.

Front

Define chromatin.

Back

Chromatin is the material that makes up chromosomes, consisting of DNA and proteins.

Front

What is the significance of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined and where spindle fibers attach during mitosis.

Front

What is the difference between DNA and RNA?

Back

DNA contains the genetic blueprint for an organism, while RNA is involved in protein synthesis and can act as a messenger.

Front

What is the purpose of telophase in mitosis?

Back

Telophase is the final stage of mitosis where the chromosomes de-condense and the nuclear envelope re-forms around each set of chromosomes.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells.
