3. The chemotherapeutic agent, paclitaxel, stabilizes microtubules (proteins that are part of the cytoskeleton) which are shown in green below. Chemotherapeutic agents are meant to kill rapidly dividing cells. A. Why is confocal microscopy an appropriate tool to study the role of paclitaxel on the cytoskeleton and the cell cycle more generally? B. Why would paclitaxel be harmful to a cell? Draw a cell that has been treated with paclitaxel during cell division.

Oogenesis

The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase. 

Cell Division

Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
