yes, the spindle fibers are connected to a protein in the center of the chromatid called a kinetochore, and it is during metaphase that they line up on the metaphase plate (equator). It is then during anaphase that they start to move toward opposite poles. And the spindle fibers are connected to centrioles and in prophase before they separate they are called a centrosome.
What else can I help you with?
What structure holds the sister chromatids to the spindle fibers?
The kinetochore, a protein complex located at the centromere of the sister chromatids, holds them to the spindle fibers during cell division. It serves as a attachment site for microtubules from the spindle apparatus.
Describe the structure and function of the spindle during mitosis?
Spindle fibers are necessary in mitosis as they help in bringing half the number of chromosomes on each side of the cell, so that when the cell divides, the chromosomes are distributed equally in both the daughter nuclei.
What form to help attach and move chromatids to the opposite poles of the cell?
Spindle Fibers
What do spindle fibers do during mitosis and meiosis?
Spindle fibers are responsible for separating and moving the chromosomes during cell division. In mitosis, they help pull sister chromatids apart to opposite poles of the cell, ensuring that each daughter cell receives a complete set of chromosomes. In meiosis, they perform a similar function but with the added complexity of separating homologous chromosomes during the first division and sister chromatids during the second division.
What is the name for the fibers that become visible during metaphase?
The strands are called chromatids. Druing prophase, the chromosomes coil and shorten and the nuclear memebrane dissolves. Each chromosome is made up of a pair of strands called chromatids, which are connected by a spindle of fibers called a centromere.
What is position of inter zonal spindle fibers?
Interzonal spindle fibers are located between the two sets of chromosomes (sister chromatids) in the center of the cell during cell division. They help to separate the chromosomes by attaching to the kinetochores on each set of sister chromatids and pulling them towards opposite poles of the cell.
During cell division this shortens to pull the chromatids apart.?

What is the process that uses spindle fibers to separate the chromatids?
The process that uses spindle fibers to separate chromatids is called anaphase. During anaphase, the spindle fibers pull sister chromatids apart towards opposite poles of the cell, ensuring each daughter cell receives an identical set of chromosomes.
What is the name for the fibers that become visible during metaphase?
The strands are called chromatids. Druing prophase, the chromosomes coil and shorten and the nuclear memebrane dissolves. Each chromosome is made up of a pair of strands called chromatids, which are connected by a spindle of fibers called a centromere.
What joins arms together and is the place where spindle fibers attach to each chromosome?
The sister chromatids (arms) are held together by centromeres. Centromeres are the site of attachment for the spindle fibers.
What is the role of the spindle fibers during mitosis?
They pull the sister chromatids apart.
