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.

When during mitosis do chromosomes attach to spindle fibers?
During mitosis a double-stranded chromosome attaches to a spindle fiber centromere.
What protein structure moves chromosomes?
During mitosis and meiosis, kinetochores move chromosomes across the spindle fibers. The kinetochores serve as vehicles and the fibers serve as roads.
Structure made of fibers help move chromosomes during mitosis?
Spindle fibers.
What is spindle fibers pull the sister chromatids apart?
During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes. The spindle fibers are composed of micro-tubules. The spindle fibers continue to shorten during anaphase in order to bring the chromosomes at two poles.During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes.

When do spindle fibers attach to chromosomes?
Spindle fibers attach to chromosomes during mitosis. Specifically, they do so in the metaphase portion of mitosis, in preparation for the splitting of the cell.
Which cellular component helps push chromosomes apart in mitosis and meiosis?
The cellular component that helps pull apart the chromosome in mitosis and meiosis are the spindle fibers. These spindle fibers are made of micro-tubules.

What is the job of centriole?
Used during Meiosis and Mitosis, only in animals. Helps with cell division.
What is the name of log-like structures that appear during cell division in animal cells and pull the chromosomes apart?
In meiosis or mitosis they are called spindle fibers which are "anchored" using centrioles.
When during mitosis do chromosomes attach to spindle fibers?
During mitosis a double-stranded chromosome attaches to a spindle fiber centromere.
What is the meaning of the word Kinetochore?
"Kinetochore" refers to a specific part of the centromere. It is a specialized structure that microtubular spindle fibers attach to during mitosis and meiosis.
Does a cytoskeleton do?
Cytoskeltons are formed by structural proteins in the protoplasm of the cell. They help the cell hold its shape, they form spindle fibers during mitosis and meiosis.

What phase is when each chromosome is connected to a spindle fiber?
During metaphase each chromosome attaches to spindle fibers. The centriole anchors the spindle fibers and helps in splitting the chromosome.
What kind of fibers do animal and plants have during mitosis?
spindle
What are chromosomes separated by during mitosis?
the spindle fibers
