CELL BIOLOGY
Choose either microtubules and microfilaments, and then explain the roles of at least 5 cellular proteins that interact with that cytoskeletal element to modify how those elements function in the cell (as opposed to their in vitro behaviors).

Expert Solution

Microfilaments are also called as actin filaments which forms a part of cytoskeleton of the eukaryotic cell along with the microtubules. The main functions of microfilaments are they take part in cytokinesis, amoeboid movement of cell,change in cell shape, cell motility etc. Besides it provide proper structure to cell and connects each part of the cell.

1. Microfilaments interacts with the myosin protein and take part in the cell motility of non muscle cells.

2. Microfilaments also interact with the cellular protein spectrin which helps in integrity of plasma membrane and maintainance of cytoskeleton.

3. Microfilaments also assist with lamins to provide structural function of the cell and controls cell mechanics

4. Filament end tracking proteins like formins, VASP associated with microfilaments which also contributes to cell structure.

5. Allograft inflammatory factor associates with microfilaments which is specific calcium binding protein.

At least almost a page. Do not copy from articles, or from anywhere. Choose either an individual application or a bundled suite of software and describe the most beneficial features as well as how they apply to your current life or future business plans. Compare these features to any rival applications based on price, system requirements, appearance, differences/similarities, ease of upgrades, etc. Determine any existing or potential competitive advantage that one company may have over another in the market and...

Explain the roles of at least THREE of the following factors on gender role development: a) prenatal hormones, b) different socialization for boys and girls, c) modeling, and d) gender schemas. Compare and contrast authoritarian, authoritative, neglectful/uninvolved, and permissive-indulgent parenting styles. For each parenting style, be sure to explain: a) whether parents are responsive to their children (are the parents warm and supportive, democratic in decision making), b) whether the parents place demands on their children (are there rules the...
