What else can I help you with?
A centriole with radiating fibers active during cell division?
The centriole with radiating fibers is known as the aster. Asters are involved in the organization of the mitotic spindle during cell division, helping to position and align the chromosomes. They also play a role in anchoring and moving the spindle apparatus.
When what phase does a DNA spindle form?
A DNA spindle, or spindle apparatus, forms during the prophase stage of mitosis and meiosis. Specifically, in prophase, the chromatin condenses into visible chromosomes, and the spindle fibers begin to extend from the centrosomes to form the spindle apparatus, which is crucial for the separation of sister chromatids during cell division.
What cell parts are more clearly visible when a cell is dividing?
During cell division, structures like the chromosomes, spindle fibers, and centrioles are more clearly visible. Chromosomes condense and can be seen as distinct entities, spindle fibers form a dynamic network between the centrioles, and the centrioles organize the spindle apparatus.
What is the name of the Net-like structure formed by the spindle fibers?
The net-like structure formed by spindle fibers during cell division is called the "spindle apparatus." It plays a crucial role in organizing and separating chromosomes during mitosis and meiosis. The spindle fibers extend from the centrosomes to the kinetochores of the chromosomes, ensuring accurate distribution of genetic material to the daughter cells.
What structure forms in prophase along which the chromosomes called?
The answer is Spindle Fibers.

What organelles are crucial to separation of chromosomes?
The spindle apparatus, made up of microtubules, and the centrosomes are crucial organelles involved in the separation of chromosomes during cell division. The spindle apparatus helps in organizing and segregating the chromosomes, while the centrosomes play a role in nucleating and anchoring the spindle fibers.

What organelles produce spindle fibers?
Centrioles. They are only found in animal cells and produce the spindle fibers during cell division (namely, Metaphase). One set is located at each pole of the cell.

The answer is Spindle Fibers.
What is a tiny microtubule structure located in the cytoplasmthat helps create the spindle fibers called?
The tiny microtubule structure located in the cytoplasm that helps create the spindle fibers is called a centriole. Centrioles are responsible for organizing the microtubules into the spindle apparatus during cell division.
What makes up the mitotic apparatus?
The mitotic apparatus is primarily composed of the mitotic spindle, which consists of microtubules that form a network to separate chromosomes during cell division. Key components include spindle fibers, which are organized by centrosomes, and motor proteins that help in the movement of chromosomes. Additionally, the mitotic apparatus includes kinetochores, which are protein structures on the chromosomes that attach to spindle fibers. Together, these components ensure accurate chromosome alignment and segregation during mitosis.
What structure holds the sister chromatids to the spindle fibers?
The kinetochore, a protein complex located at the centromere of the sister chromatids, holds them to the spindle fibers during cell division. It serves as a attachment site for microtubules from the spindle apparatus.
Which type of cell has spindle fibers?
Animal cells have spindle fibers in them.
What structures are made of hollow protein fibers and are used in the movement of chromosomes during a cell division?
Spindle fibers, also known as microtubules, are hollow protein fibers involved in the movement of chromosomes during cell division. These fibers form the spindle apparatus, which helps separate the chromosomes and pull them to opposite ends of the cell during both mitosis and meiosis.
