Proteins can assemble as liquid droplets that are not bounded by a membrane in either the cytoplasm or nucleus A protein can separate into different organelles dependent on the phase of the cell cycle Proteins that are assembled in one phase of the cell cycle and degraded in the next are said to undergo phase separation Signal sequences can target proteins assembled in the cytoplasm into the lumen of the endoplasmic reticulum
- Describe the similarities and differences between the cytokinesis mechanisms found in animal cells versus those in plant cells.VISUALIZE Sketch a roughly cuboidal cell preparing to divide. Indicate the orientation of the preprophase band and the site where the new cell walls of the daughter cells will form.In the context of cell biology, what do we mean by form follows function? What are a least two examples of this concept?
- Describe the mitotic spindle. Include what it is made of, how it forms, and what its role is in cell division.WRITE ABOUT A THEME: ORGANIZATION The properties oflife emerge at the biological level of the cell. The highly regulated process of apoptosis is not simply the destruction of acell; it is also an emergent property. Write a short essay (about100–150 words) that briefly explains the role of apoptosis inthe development and proper functioning of an animal, and describe how this form of programmed cell death is a process thatemerges from the orderly integration of signaling pathways.What cellular mechanism(s) ensure that passage through the cell cycle is unidirectional and irreversible? What molecular machinery underlies these mechanism(s)?
