Tubulin is to microtubules as actin is to what?
Tubulin is to microtubules as actin is to microfilaments. Both tubulin and actin are protein subunits that polymerize to form structural components of the cytoskeleton in eukaryotic cells. While tubulin assembles into hollow tubes called microtubules, actin polymerizes to form thin filaments known as microfilaments, which play crucial roles in cell shape, motility, and division.
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.
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.
Are microtubules tubelike proteins?
Microtubules are not proteins themselves, but rather structures made up of protein subunits called tubulins. These tubulins assemble together to form long, hollow tubes that play a critical role in many cellular processes, including cell division and intracellular transport.
Thin hollow cylinders made of protein?
Thin hollow cylinders made of protein that provide structural support for eukaryotic cells are microtubules. Microtubules are involved in nuceic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.
What are microtubules made of?
Microtubules are made of protein subunits called tubulin. These tubulin subunits polymerize to form long, hollow tubular structures that are essential for various cellular processes such as cell division, cell shape maintenance, and intracellular transport.
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.

The microtubules that form centrioles and spindle fibers are made of hollow tubes of?
The microtubules that form centrioles and spindle fibers are made of tubulin protein subunits arranged in a tube-like structure. These hollow tubes provide structural support and play a crucial role in cell division by helping to organize and separate chromosomes.
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 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.
Microtubules into tubulin units?
Microtubules are made up of repeating units called tubulin. Tubulin is a protein that assembles into a structure that forms the walls of the microtubule, providing structure and stability. The tubulin units polymerize to form the long, hollow structures of microtubules essential for various cellular processes like cell division and intracellular transport.
Thin hollow cylinders made of protein?
Thin hollow cylinders made of protein that provide structural support for eukaryotic cells are microtubules. Microtubules are involved in nuceic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.
Cilia and flagella are made of protein filaments called?
Microtubules, specifically composed of tubulin protein subunits, form the structural core of cilia and flagella in eukaryotic cells. These filaments provide the rigidity and flexibility necessary for these organelles to move and function effectively in various cellular processes.
What structures make up the fibers of the mitotic spindle?
The mitotic spindle is composed of microtubules, which are dynamic structures made up of tubulin protein subunits. It consists of three main types of microtubules: kinetochore microtubules that attach to the chromosomes, polar microtubules that interact with each other to help push the poles of the cell apart, and astral microtubules that anchor the spindle poles to the cell membrane.
