The hollow tubes of protein that help maintain the shape of the cell is what?
The hollow tubes of protein that help maintain the shape of the cell are called microtubules. They are part of the cytoskeleton and play crucial roles in cell structure, cell division, and intracellular transport.
What is a protein in microtubules that forms hollow tubes?
cytoskeleton
What is the function of tubulin?
Tubulin is a protein that polymerizes to form microtubules, which are essential components of the cytoskeleton. Microtubules play roles in cell structure, cell division, intracellular transport, and cell motility.
What region of the chromosome serves as the attachment site for microtubules during Cell division?
The kinetochore is the region of the chromosome that serves as the attachment site for microtubules during cell division. It is a protein structure that forms on the centromere of a chromatid. Kinetochore microtubules connect the chromatids to the mitotic spindle to aid in the separation of chromosomes during mitosis.
Spindle fibers are made of hollow tubes of protein called what?
Spindle fibers are made of microtubules, which are composed of the protein tubulin. These microtubules play a critical role in the segregation of chromosomes during cell division.

What is a protein in microtubules that forms hollow tubes?
cytoskeleton
Is actin a microtubule or are they distinct structures within the cell?
Actin and microtubules are distinct structures within the cell. Actin is a protein that forms thin filaments, while microtubules are made of tubulin proteins and form a network of hollow tubes. Both actin and microtubules play important roles in cell structure and movement.

Spindle fibers are made of microtubules, which are composed of the protein tubulin. These microtubules play a critical role in the segregation of chromosomes during cell division.
What are hollow tubes made of spherical protein subunits called tubulins?
Hollow tubes made of spherical protein subunits called tubulins are known as microtubules. These microtubules play a crucial role in cell structure, cell division, intracellular transport, and cellular movement in all eukaryotic cells. The dynamic assembly and disassembly of microtubules are tightly regulated in the cell.
Spindle fibres are composed of?
Spindle fibers are composed of microtubules, which are long, filamentous structures made up of tubulin protein subunits. These fibers play a crucial role in separating chromosomes during cell division by attaching to the chromosomes and guiding their movement to opposite poles of the cell.
What makes microtubules?
Microtubules are composed of tubulin protein subunits that polymerize into long, hollow tubes. They are essential for cell structure, intracellular transport, and cell division. Microtubules dynamically assemble and disassemble, allowing cells to quickly reorganize their structure as needed.
Is tubulin a motor protein?
No, tubulin is not a motor protein. It is a structural protein that helps form microtubules, which are important for cell structure and transport. Motor proteins, on the other hand, are responsible for moving cellular components along microtubules.
What is the cytoskeleton and what are the two of its major components?
The cytoskeleton is a network of filamentous proteins that holds the organelles in place and maintains the shape of a cell. It is composed of microtubules (composed of the protein tubulin), intermediate fibers, and microfilaments.
What cytoskeleton fiber is a strait hollow tube of protein?
Microtubules are the cytoskeleton fibers that are straight hollow tubes of protein. They are made up of tubulin protein subunits and play a crucial role in various cellular processes such as cell division, intracellular transport, and cell shape maintenance.
