Cell Cycle, Mitosis, Cancer, Cell Differentiation

Front

What happens during prophase of mitosis?

Back

DNA condenses into chromosomes, centrioles and spindle fibers appear.

Front

What is an oncogene?

Back

A mutated form of a proto-oncogene that leads to uncontrolled cell growth, contributing to cancer.

Front

How many stages are there in mitosis?

Back

There are 4 stages in mitosis: prophase, metaphase, anaphase, and telophase.

Front

What are sister chromatids?

Back

Two identical halves of a chromosome that are joined together at the centromere.

Front

What is the end result of mitosis?

Back

The end result of mitosis is 2 identical body cells.

Front

What is the role of tumor suppressor genes?

Back

Tumor suppressor genes help regulate cell division and prevent uncontrolled growth.

Front

Define cell differentiation.

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type.

Front

What is the function of spindle fibers during mitosis?

Back

Spindle fibers help separate the sister chromatids and pull them to opposite poles of the cell.

Front

What occurs during metaphase?

Back

During metaphase, chromosomes line up in the middle of the cell and attach to spindle fibers.

Front

What is the significance of DNA replication?

Back

DNA replication ensures that each new cell receives an exact copy of the DNA.
