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.
During mitosis the centrioles form or organize the mitotic apparatus which is known as what?
spindle
What structures allow chromosomes to separate and move during mitosis?
The spindle apparatus, made up of microtubules, plays a key role in chromosome separation and movement during mitosis. The centrosomes help organize and control the spindle apparatus. The kinetochores, located at the centromere of each chromosome, attach to the microtubules and facilitate chromosome movement.
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.
During what cell cycle phase is the spindle formed?
The spindle is formed during the prophase stage of mitosis or meiosis. In prophase, microtubules organize into a structure called the spindle apparatus, which helps separate the chromosomes during cell division.
What is the function of the spindle apparatus?
Microtubules
What is the longest stage in mitosis?
The longest stage in mitosis is typically prophase, as it involves the condensation of chromatin into visible chromosomes, the breakdown of the nuclear envelope, and the organization of the mitotic spindle apparatus.
What is the function of cemtrosomes during mitosis?
I assume you mean centrosome, not cemtrosome. The centrosome is a microtubule organizing center made up of two centrioles. In mitosis, it creates spindle apparatus microtubules, which are then used to separate the chromosomes into the two daughter cells. It is worth noting that a centrosome is not required to create the spindle.
What equally divides chromatids between offspring cells?
The spindle apparatus equally divides chromatids between offspring cells during cell division through a process called mitosis. The spindle fibers attach to each chromatid and pull them apart to ensure that each daughter cell receives an equal number of chromosomes. This ensures genetic stability and proper distribution of genetic material.
In which phase do spindle apparatus has disassembled and the spindle fibers dissolve?
Telophase
What anchors the spindle in mitosis?
centriols
What is used in meiosis but not in mitosis?
Spindle
