Question

If a cell needs to make a thin actin filament thicker it will use what?

Select one:

Capping protein

Cohesion protein

Crosslinking protein

Tubulin

Bundling protein

Answer 1

Ans : 5. Bundling protein

1. Capping proteins control access to the free barbed ends of actin filaments and affecting actin filament elongation.

2. Cohesin protein complex regulates the separation of sister chromatids during cell division.

3. cross-linking proteins are used to chemically bind the protein molecules.

4. tubulin protein, α- and β-tubulins polymerize into microtubules, a major component of the eukaryotic cytoskeleton

5. Bundling proteins contain repeated actin-filament-binding domains. Actin Filaments are assembled like bundles by the bundling proteins.
