U5 Cell Cycle Review 2024 HBio

Front

What is the normal function of a proto-oncogene?

Back

Proto-oncogenes are responsible for moving the cell through the cell cycle.

Front

In which phase is a cell that has completed mitosis and is ready for cytokinesis?

Back

The cell is in the telophase.

Front

If a cell does not grow or divide but continues to perform normal functions, it is said to be in what phase?

Back

G-zero phase.

Front

What holds the two sister chromatids together?

Back

The centromere.

Front

What is the correct order of the cell cycle phases?

Back

D A C E B.

Front

What is the role of the centrioles during cell division?

Back

Centrioles help in the formation of spindle fibers that separate chromosomes.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm.

Front

What happens during prophase?

Back

Chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.
