What else can I help you with?
During which step in mitosis do the chromosomes get attached to the spindle apparatus?
During the metaphase stage of mitosis, the chromosomes become attached to the spindle apparatus.
What does a spindle apparatus do in mitosis?
Separation of chromatids during anaphase .
What part of the chromosome is the spindle apparatus attach?
The spindle apparatus attaches to the centromere region of the chromosome. This is where the kinetochore proteins are located, which help in the attachment of spindle microtubules to the chromosome during cell division.
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 functions to separate chromatids during cell division?
spindle apparatus
During mitosis the centrioles form or organize the mitotic apparatus which is known as what?
spindle
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.
How does spindle apparatus distribute chromosomes to the daughter cells?
The spindle apparatus is responsible for aligning and segregating chromosomes during cell division. The microtubules of the spindle apparatus attach to the centromere of chromosomes and actively move them to opposite poles of the cell during anaphase of mitosis or meiosis. This ensures that each daughter cell receives the correct number of chromosomes.
When does the spindle attach to the kinetochores?
The spindle attaches to the kinetochores during prometaphase, where the microtubules from the spindle apparatus interact with the kinetochores on sister chromatids. This attachment is essential for proper chromosome alignment and segregation during cell division.
What is the function of the spindle apparatus?
Microtubules
In which phase do spindle apparatus has disassembled and the spindle fibers dissolve?
Telophase
What is the cytoskeletal structure that pulls chromosome apart?
The cytoskeletal structure responsible for pulling chromosomes apart during cell division is the spindle apparatus. It consists of microtubules that attach to the chromosomes and exert forces to separate them into two daughter cells. The spindle apparatus is essential for ensuring the accurate distribution of genetic material during cell division.
