The solid linear cytoskeletal elements having a diameter of 6 nm and made up of a single type of monomer are known as :
1. Microtubules
2. Microfilaments
3. Intermediate filaments
4. Lamins
Consider the given two statements:
Statement I | Only eukaryotes have cytoskeleton components. |
Statement II | The cell wall is the only deciding factor for many bacterial cell shapes. |
1. | Both I and II are correct and II explains I |
2. | Both I and are correct but II does not explain I |
3. | I is correct and II is incorrect |
4. | Both I and II are incorrect |
