Cell Cycle Overview

The cell cycle consists of distinct phases regulated by crucial checkpoints. During interphase, cells grow and prepare for division through G1, S, and G2 phases, followed by mitosis (M phase).

Definition: The cell cycle is the sequence of growth and division that cells go through to produce new daughter cells.

Highlight: Cells can temporarily or permanently exit the cycle into G0 phase to become specialized.

Example: During G1, cells increase in size and produce RNA and proteins before DNA replication in S phase.

Vocabulary: Checkpoints are regulatory mechanisms ensuring proper cell cycle progression at G1, G2, and M phases.

Mitosis Stages

Mitosis produces two genetically identical daughter cells through a series of carefully orchestrated stages. The process is essential for growth and repair of damaged tissues.

Definition: Mitosis is the process of nuclear division resulting in two genetically identical nuclei.

Highlight: Key stages include prophase, metaphase, anaphase, telophase, and cytokinesis.

Example: During prophase, chromosomes condense and become visible as the nuclear envelope breaks down.

Vocabulary: Sister chromatids are identical copies of DNA joined at the centromere.

View

Late Mitotic Events

The final stages of mitosis involve precise chromosome separation and cytoplasmic division.

Definition: Cytokinesis is the division of cytoplasm following nuclear division.

Highlight: Plant cells undergo cytokinesis differently, forming a cell plate rather than pinching in.

Example: During anaphase, spindle fibers pull sister chromatids to opposite poles using energy from mitochondria.

Cell Cycle Errors and Cancer

Disruptions in normal cell cycle regulation can lead to serious consequences, particularly cancer development.

Definition: Cancer is a group of diseases characterized by uncontrolled cell division.

Highlight: Tumor suppressor genes play a crucial role in preventing uncontrolled cell growth.

Example: UV light exposure can affect mitosis rates and potentially lead to cancer development.

View

Cancer Treatment Approaches

Cancer treatments often target specific stages of the cell cycle to prevent tumor growth.

Definition: Chemotherapy drugs work by disrupting various stages of the cell cycle.

Highlight: Treatments can target DNA replication or spindle formation during mitosis.

Example: Hair loss during chemotherapy occurs because rapidly dividing hair follicle cells are also affected by treatment.

I love this app so much, I also use it daily. I recommend Knowunity to everyone!!! I went from a D to an A with it :D

Philip, iOS User

The app is very simple and well designed. So far I have always found everything I was looking for :D

Lena, iOS user

I love this app ❤️ I actually use it every time I study.
