The organelles in question are the centrioles. During cell division, the centrioles move to oppose poles of the cell and synthesise the microtubules that make up the spindle apparatus, which separates the sister chromatids during the stage of anaphase.
Thespindle fibres are formed by the centrosomes not the cenrioles.The centrioles come to the MTCs ( micro tubules organising centers) which are present in the centrosomes which make up the spindle fibers on which the chromosomes are held.
Spindle fibers are present in both prophase and metaphase stages of mitosis. In prophase, the spindle fibers start to form and separate the duplicated chromosomes. In metaphase, the spindle fibers attach to the centromeres of the chromosomes and align them along the cell's equator.
Meosis is a reductional division, which means the primary cell has to divide twice thus giving four haploid cells. Spindle fibers are formed at Anaphase 1 (of the first division cycle) and Anaphase 2 (of the second division)
During Prophase
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.
Spindle fibers are formed by micro tubules.They are organized by centrioles.
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.
Spindle fibers are formed during the metaphase stage of mitosis (cell division) when the chromosomes are tightly condensed and aligned at the center of the cell. Spindle fibers pull the chromosomes in opposite directions toward the opposite poles thus allowing the daughter cells to obtain a copy of the genome
Spindle fibers are not cells but components of cells which are essential in the process of cell division. In animal cells, the spindle fibers are formed by centrioles; however, in plant cells, there is no apparent organizer of the spindle fibers.
Spindle Fibers
Spindle fibers are composed of microtubules, which are long, threadlike structures made of a protein called tubulin. These spindle fibers play a key role in cell division by helping to separate chromosomes during mitosis and meiosis.
It's called a spindle. Here's the definition, according to The American Heritage Dictionary of the English Language:The spindle-shaped achromatic structure, composed of microtubules, along which the chromosomes are distributed in mitosis and meiosis.
The name for the network of microtubules along which the chromosomes move during cell division is called the spindle fibers. These spindle fibers attach to the chromosomes and pull them in half.
The organelles in question are the centrioles. During cell division, the centrioles move to oppose poles of the cell and synthesise the microtubules that make up the spindle apparatus, which separates the sister chromatids during the stage of anaphase.
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.
Thespindle fibres are formed by the centrosomes not the cenrioles.The centrioles come to the MTCs ( micro tubules organising centers) which are present in the centrosomes which make up the spindle fibers on which the chromosomes are held.
