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.

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 do spindle fibers do during mitosis and meiosis?
During mitosis and meiosis the spindle fibers allow the chromosomes to line up along the equator of the cell. The chromosomes slide to either pole during cell division.
What structure holds the sister chromatids to the spindle fibers?
Sister chromatids are held together by centromere and are attached to the spindle fibres by kinetochores during cell division.
What form to help attach and move chromatids to the opposite poles of the cell?
Spindle Fibers
The phase of mitosis in which microtubules connect the centromere of each chromosome to the poles of the pindle?
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.

What is the name of the fibers that line the chromosomes up at the equator of the cell?
the answer is spindle!
What form to help attach and move chromatids to the opposite poles of the cell?
Spindle Fibers
Chromosomes attached to the spindle fibers by undivided structures is called what?
Chromosomes attached to the spindle fibers by undivided structures are called sister chromatids. Sister chromatids are two identical copies of a chromosome that are connected at the centromere until they separate during cell division.
What holds chromtids togrther and to the spindle fibers?
Chromatids are held together by a protein complex called the cohesin complex. The attachment of chromatids to the spindle fibers is mediated by protein structures called kinetochores, which assemble on the centromere region of the chromatids. These interactions are crucial for the accurate segregation of chromosomes during cell division.

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.
What happens in a cell during anaphase?
Anaphase: Spindle fibers shorten, the kinetochores separate, and the chromatids (daughter chromosomes) are pulled apart and begin moving to the cell poles. In summery identical sets of chromosomes are moved to opposite sides of the cell.
What are the functions of the spindle fibers and the centrioles?
The centrioles are similar to a railing at the two ends of a cell. The spindle fibers attach to the chromosomes (matching pairs) which are lined up in the middle of the cell. This spot is called the equator. The spindle fibers are also attached to the centrioles. The fibers begin to pull the chromosomes apart while holding fast to the centrioles.
