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.
When do the centromeres split and form the chromatids?
Centromeres split during cell division in the mitotic phase called anaphase. As the sister chromatids are pulled apart towards opposite poles of the cell, the centromeres divide, forming individual chromatids that will become separate chromosomes in the daughter cells.
How do centromeres that join sister chromatids split during cell division?
During cell division, centromeres that join sister chromatids split by a process called mitosis. This involves the separation of the sister chromatids, with each chromatid moving to opposite ends of the cell. This ensures that each new cell receives a complete set of chromosomes.
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 is a cell structure consisting microtubules which forms during early mitosis and plays a role in cell division?
The structure you are referring to is the mitotic spindle. It is made up of microtubules that help separate the chromosomes during cell division to ensure each daughter cell receives the correct number of chromosomes.
What is the structure called that holds two chromatids together?
The structure that holds two chromatids together is called a centromere. It is a region of the chromosome where the two sister chromatids are attached and where the microtubules of the spindle fibers attach during cell division.
What are Microtubles that extend from the poles of cell to the centromeres during cell division called?
spindle fibers
What is the phase of mitosis dose the microtubules at eatheir and of a cell attach to the chromsomes and engagein a tug of war?
This phase of mitosis is called metaphase. During metaphase, the microtubules from opposite poles of the cell attach to the centromeres of the chromosomes. The microtubules then exert force to align the chromosomes at the center of the cell, forming the metaphase plate.
Microtubules that extend from the poles of a cell to the centromers during cell division are called?
spindle fibers
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.
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.
The assembly of microtubules is responsible for the movement of chromosomes during anaphase is called what?
The assembly of microtubules responsible for moving chromosomes during anaphase is called the mitotic spindle. It is composed of microtubules that attach to chromosomes and help separate them into two new daughter cells during cell division.
The framework of microtubules that appears in cell division which eventually moves the chromatids apart is called the?
spindle apparatus
What are the fibers that shorten and pull the chromatids apart called?
The fibers that shorten and pull the chromatids apart are called microtubules. During cell division, microtubules form the spindle apparatus and attach to the chromosomes to facilitate their separation.
