=In this stage the nuclear envelope breaks down so there is no longer a recognizable nucleus. Some mitotic spindle fibers elongate from the centrosomes and attach to kinetochores, protein bundles at the centromere region on the chromosomes where sister chromatids are joined. Other spindle fibers elongate but instead of attaching to chromosomes, overlap each other at the cell center.=

What is the phase in mitosis where the nuclear membrane disappears?

"scientist have not discovered WHY it happens"It does not matter if scientists have discovered it or not, but the nuclear membrane disappears during PROPHASEHope this helped!!!


What phase of mitosis begins when the nuclear membrane begins to fade?

The phase of mitosis that begins when the nuclear membrane starts to fade is called prometaphase. During prometaphase, the nuclear membrane breaks down, allowing the spindle fibers to attach to the chromosomes.


What does the correct chromosomal condition at prometaphase of mitosis look like?

The correct chromosomal condition at prometaphase of mitosis is when the chromosomes are fully condensed and aligned along the metaphase plate in preparation for segregation. Each chromosome consists of two sister chromatids held together by a centromere. The spindle fibers are attached to the kinetochores on each sister chromatid to ensure proper separation during anaphase.


What disappears during prometaphase?

During prometaphase, the nuclear envelope breaks down, allowing the chromosomes to be released from the nucleus. The nuclear membrane disappears, leading to the chromosomes being able to interact with the mitotic spindle fibers for proper alignment and separation during cell division.


What phase do chromosomes attach to spindle fibers?

Chromosomes attach to spindle fibers during metaphase of mitosis. This attachment ensures that the chromosomes are properly aligned at the metaphase plate before they are separated and pulled to opposite poles of the cell during anaphase.

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.


Is prometaphase in meiosis?

No, prometaphase is a stage in mitosis, not meiosis. In meiosis, there is a prophase I stage that is similar to prometaphase in mitosis.


What is the Phase of mitosis in which microtubules connect thecentromere of each chromosome to the poles of spindle?

The phase you are referring to is called prometaphase. During prometaphase, the microtubules attach to the kinetochores at the centromere of each chromosome, allowing them to move and align properly along the metaphase plate in preparation for separation during anaphase.

What phase do microtubules attach to kinetochores?

Microtubules attach to kinetochores during the prometaphase stage of cell division. This attachment is essential for the proper alignment and segregation of chromosomes during mitosis.


Which stage of the following does nuclear envelope break down?

The nuclear envelope breaks down during prometaphase of mitosis and prophase of meiosis. This breakdown allows the chromosomes to be released from the nucleus and prepare for the subsequent stages of cell division.


What subphase of mitosis is it when an array of microtubles called spindle fibers now extend between the two centrioles?

This subphase is known as prometaphase in mitosis. During prometaphase, the nuclear envelope breaks down, allowing the spindle fibers to interact with the condensed chromosomes. This is a critical stage for the proper alignment and separation of chromosomes during cell division.

When do microtubules attach to kinetochores?

Microtubules attach to kinetochores during prometaphase of mitosis, forming the mitotic spindle apparatus. This attachment is crucial for proper chromosome alignment and segregation during cell division.
