Cell Cycle & Mitosis Flashcard

Front

What are the stages of the cell cycle in order?

Back

G1, S, G2, M

Front

What is a common characteristic of all cancers?

Back

Uncontrolled cell growth

Front

What occurs during telophase?

Back

2 new nuclei form

Front

What are cancer-promoting substances called?

Back

Carcinogens

Front

What is the result of mitosis?

Back

Two identical cells with all of the original chromosomes

Front

Define interphase.

Back

The phase of the cell cycle where the cell prepares for division, consisting of G1, S, and G2 phases.

Front

What happens during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in two copies of each chromosome.

Front

What is the role of cyclins in the cell cycle?

Back

Cyclins are proteins that regulate the progression of the cell cycle by activating cyclin-dependent kinases.

Front

What is the difference between benign and malignant tumors?

Back

Benign tumors are non-cancerous and do not spread, while malignant tumors are cancerous and can invade nearby tissues.

Front

What is the function of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes and pull them to opposite sides of the cell.
