What else can I help you with?
What is the job of centriole?
Used during Meiosis and Mitosis, only in animals. Helps with cell division.
What happen before prophase occur?
During prophase, the chromatin fibers present in the nucleus coil tightly into observable chromosomes. The centrosomes move away from each other and spindle microtubules begin to grow from them; this marks the formation of the mitotic spindle.
Explain why prophase is the longest phase in mitosis?
because the most things happen in it. centrioles grow, spindle fibers arrange on chromosomes, and the cell grows exponentially.
Which of these is not a way of classifying muscles?
the type of muscle fibers
What event occurs during metaphase?
The chromosomes attach to a spindle fiber across the equator of the cell.
Which type of cell has spindle fibers?
Animal cells have spindle fibers in them.
Cell structures made of individual microtube fibers that are involved in moving chromosomes during cell division are called?
Spindle fibers. These structures form the mitotic spindle and play a crucial role in separating chromosomes during cell division.
What fibers stretch across a cell during mitosisis?
spindle fibers
What is the relationship between microtubules and spindle fibers in cell division?
Microtubules are the building blocks of spindle fibers, which are essential for cell division. During cell division, microtubules form the spindle fibers that help separate chromosomes and ensure each new cell receives the correct number of chromosomes. In summary, microtubules are the structural components of spindle fibers that play a crucial role in the process of cell division.
What cell organelle that helps in division and emits spindle fibers?
Spindle fibers are formed by micro tubules.They are organized by centrioles.
What is the structure for spindle fibers?
During the metaphase of cell division, the spindle fibers radiate from the centrioles at the opposite poles of the cell. When the spindle fibers start to pull the chromosomes to opposite poles, this marks the anaphase of cell division.
What is the relationship between centrosomes and spindle fibers?
Spindle Fibers are formed between centrosomes. Centrosomes migrate to opposite ends of the cell during cell division. The spindle fibers function is to anchor the centrosomes and chromosomes into the poles. The chromosomes then reel them selves in using the spindle fiber.
During which phase of cell division process are chromosomes attached to the spindle fibers?
Chromosomes are attached to spindle fibers during the metaphase phase of the cell division process.
What happends to the spindle fibers in telophase?
In telophase, the spindle fibers start to disassemble as the chromosomes reach the opposite ends of the cell. This disassembly process helps in the formation of two separate nuclei and marks the final stage of cell division.
What cell parts are more clearly visible when a cell is dividing?
During cell division, structures like the chromosomes, spindle fibers, and centrioles are more clearly visible. Chromosomes condense and can be seen as distinct entities, spindle fibers form a dynamic network between the centrioles, and the centrioles organize the spindle apparatus.
During metaphase the centrometers attach to what structures?
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.
How are microtubules and spindle fibers involved in the process of cell division?
Microtubules and spindle fibers play crucial roles in cell division. Microtubules help separate chromosomes during mitosis by forming the mitotic spindle, a structure that helps move and align chromosomes. Spindle fibers, which are made of microtubules, attach to chromosomes and help pull them apart during cell division. Overall, microtubules and spindle fibers ensure that each daughter cell receives the correct number of chromosomes.
