What structures is only present in mitosis?
The structure that is only present during mitosis is the mitotic spindle. This structure is composed of microtubules and is responsible for separating and pulling apart the sister chromatids to opposite poles of the cell. The formation of the mitotic spindle occurs during the prophase stage of mitosis and is crucial for ensuring accurate chromosome segregation. Once mitosis is complete, the spindle disassembles and is no longer present in the daughter cells.
During which phase of mitosis are chromosomes attaching to the spindle?
Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
What are chromosomes separated by during mitosis?
the spindle fibers
Are Asters absent in plant cell mitosis or animal cell mitosis?
Asters are present in animal cell mitosis but absent in plant cell mitosis. In animal cells, asters are formed by the centrosomes during the organization of the mitotic spindle, helping to anchor the spindle fibers. In contrast, plant cells lack centrosomes and instead form a spindle apparatus without the formation of asters, relying on microtubules that emanate from the nuclear envelope and other structures.
What structures do the spindles originate?
Spindle fibers originate from structures called centrosomes, which are located at opposite poles of the cell during cell division. Each centrosome contains a pair of centrioles that help organize microtubules, forming the mitotic spindle. The spindle fibers are primarily composed of microtubules, which extend and attach to chromosomes at their kinetochores to facilitate their movement during mitosis.
When do spindle fibers attach to chromosomes?
Spindle fibers attach to chromosomes during metaphase of mitosis. Special protein structures called kinetochores on the chromosomes interact with the spindle fibers to ensure proper alignment and segregation of the chromosomes during cell division.
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.

During this stage of mitosis, when do the chromosomes become attached to the spindle fibers?
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
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 which phase of mitosis are chromosomes attaching to the spindle?
Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
When during mitosis do chromosomes attach to spindle fibers?
Chromosomes attach to spindle fibers during metaphase of mitosis. This is when the chromosomes align at the cell's equator, forming a metaphase plate. The spindle fibers attach to the centromere region of the chromosomes.
During what phase of mitosis does the spindle disperse?
The answer is telophase.
When do spindle fibers first become visible?
Spindle fibers first become visible during prophase of mitosis, when the chromosomes condense and the nuclear envelope breaks down. The spindle fibers are key structures involved in aligning and separating the chromosomes during cell division.
What kind of fibers do animal and plants have during mitosis?
spindle
What does a spindle apparatus do in mitosis?
Separation of chromatids during anaphase .
What are chromosomes separated by during mitosis?
