Cell Cycle & Cell Division (17.1 and 17.2)

Front

What is the process by which a cell divides into daughter cells?

Back

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

Front

Which type of reproduction involves a single parent and results in offspring genetically identical to the parent?

Back

Asexual reproduction is a type of reproduction that involves only one parent, producing offspring that are genetically identical to the parent.

Front

During which phase of mitosis do chromosomes line up across the center of the cell?

Back

Metaphase is the phase of mitosis where chromosomes align at the cell's equatorial plane.

Front

What is the threadlike structure of DNA and protein that contains genetic information?

Back

A chromosome is a threadlike structure made of DNA and protein that carries genetic information.

Front

What is the first and longest phase of mitosis where genetic material condenses and chromosomes become visible?

Back

Prophase is the first and longest phase of mitosis, during which chromatin condenses into visible 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.

Front

What is the role of chromatin in the cell cycle?

Back

Chromatin is the relaxed form of DNA that allows for gene expression and DNA replication during the interphase of the cell cycle.

Front

What happens during anaphase?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the significance of the centromere?

Back

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

Front

What occurs during telophase?

Back

During telophase, the chromosomes reach the poles, decondense back into chromatin, and the nuclear envelope re-forms around each set of chromosomes.
