What else can I help you with?
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.
Can you explain 'prophase' in one sentence?
Yes, prophase is a part in the cell cycle of mitosis where spindle fibers form and attach to chromosomes.
What are the events that take place in prophase?
Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to opposite sides of the nulceus. Spindle fibers form a bridge between the ends of the cell. the Nuclear envelope breaks down.
What happens during prometaphase?
=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.=
Briefly describe what happens during prophase?
During prophase, the nuclear membrane breaks down, the chromatin condenses into chromosomes, and the centrioles move to opposite poles of the cell. This prepares the cell for cell division and the separation of genetic material.
What structure disappears during telophase?
The structure that disappears during telophase is the mitotic spindle, which is responsible for separating the sister chromatids during cell division. As the cell prepares to complete division, the mitotic spindle breaks down and is no longer needed.
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 phase in mitosis happens first?
The first phase in mitosis is prophase, during which the chromosomes condense, the nuclear envelope breaks down, and the mitotic spindle fibers begin to form.
Can you explain 'prophase' in one sentence?
Yes, prophase is a part in the cell cycle of mitosis where spindle fibers form and attach to chromosomes.
What is the first stage of mitos is?
The first stage of mitosis is prophase. During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle fibers begin to form.
What is the initial visible phase of mitosis?
The initial visible phase of mitosis is prophase. During prophase, the nuclear envelope breaks down, chromosomes condense, and the mitotic spindle begins to form.
What would happen if your ball joint breaks?
The ball joint holds the spindle on most assemblies and if it breaks then there will be a loss of control. Most go bad and you can feel the play from up to down on the wheel. But extreme circumstances would be it separating and that is never a good thing. Replace as necessary.
What happens in protometaphase?
In protometaphase, the nuclear envelope breaks down, allowing the chromosomes (which have already condensed in prophase) to interact with the spindle fibers. This stage prepares the cell for metaphase, where the chromosomes align at the cell's equator.
What breaks down food into what that cells can absorb What breaks down food?
1.) What breaks down food into what that cells can absorb what breaks down food ? The answer is B wich is Digestion . = Lexy.B
What are the events that take place in prophase?
Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to opposite sides of the nulceus. Spindle fibers form a bridge between the ends of the cell. the Nuclear envelope breaks down.
What is the organelle that forms spindle fibers that split and pull chromosomes to opposite ends of the cell?
The organelle responsible for forming spindle fibers during cell division is the centrosome. The centrosome is composed of two centrioles and plays a critical role in organizing and anchoring the spindle fibers that help separate the chromosomes during mitosis.
What happens during prometaphase?
=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.
