Cell Cycle

The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to duplication of its DNA (DNA replication) and division of cytoplasm and organelles to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods.

The cell cycle plays a significant role in understanding cancer. The purpose of the checkpoint is to identify cells that should not reproduce and are labeled for destruction. In cancer, the checkpoints don't recognize the malignant cells and allow them to continue to undergo mitosis. In cancer cells, the cells produce an enzyme that speeds up the cell cycle and the cancerous cells undergo mitosis frequently.  

Prompts

Discuss the cell cycle

Identify the stages of cell development

Explain interphase

Explain the function of G1, S, G2 

Why does a cell enter G0 (G knot)

Please develop and submit a presentation that demonstrates your understanding of the cell cycle. Please address the "Prompt" suggestions in your presentation.

Mitosis/Cytokinesis (Cell Division)

Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis, which occur in animal cells.

Mitosis occurs in most cells but not in the sex cells, sperm and egg. The sex cells undergo the process of meiosis.

Mitosis

Mitosis is the process of cell division

Please review the following material:

Take a few minutes to examine the microscope slide of mitosis. Please identify each of the phases of mitosis in the slide

Prompts

Explain interphase

Discuss PMAT

Explain the role of the centrosomes

Address microtubules 

Who was Walther Flemming?

Explain the function of cytokinesis

Please develop and submit a presentation that demonstrates your understanding of mitosis and cytokinesis.  Please address the prompt suggestions in your presentation.

Meiosis

Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes (eggs and sperm)

Identify 2 types of genetic disorders that are a result of meiosis

Prompts

Discuss crossing over in meiosis

Please define the word homologous and how it relates to meiosis

Explain gametes and haploid cells

Discuss how recombination benefits evolution  

How does the development of the egg and sperm differ?

Please develop and submit a presentation that demonstrates your understanding of meiosis. Please address the prompts in your presentation.
