What evidence suggests that during anaphasespindle fibers shorten at the kinetochore and not at the base of the mitotic spindle?

Bleaching the middle of fluorescing microtubules reveals the answer to this question. The bleached section does not move during the shortening of the spindle fibers which indicates that the shortening is occurring near the kinetochore.

What is the kinetichore?
Kinetochores are proteinaceous region adjacent to the centromere of a sister chromatid pair Kinetochores do the interacting with the mitotic spindles The mitotic spindles with which kinetochores interact are called kinetochore microtubules
What organelles are crucial to separation of chromosomes?
The centrosomes, fit with two centrioles, produce spindle fibers. Some, specifically called kinetochore fibers, will attach to the centromeres of the chromosomes.
What is the function of microtubules during anaphase?
During the first stage of anaphase the kinetochore microtubules retract pulling the two sister chromatids apart towards the poles. During the second stage of anaphase the mitotic poles that is mared by the centrosomes themselves separate by the elongation of a specific type of non-kinetochore microtubule called as the polar microtubule.
Why is the structure responsible for the movement of chromosome during anophase?
The Centrosome. It forms Centrioles which form spindle fibers. Some of the spindle fibers attach to the Kinetochore located on the Centromere of chromosomes. The spindle fibers work in conjunction with motor proteins to facilitate disjunction.
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 noun for mitotic?
The word 'mitotic' is the adjective form of the noun mitosis.
To which part of the centromere do mitotic spindle fibers attach during prometaphase?
The centromeres of chromosomes attach to the spindle fibers during metaphase. The spindle fibers bring about the separation of sister chromosomes to the opposite poles. When spindle fibers do not attach to the centromeres, the doubling of chromosomes leads to polyploidy in the cell.
Classmate suggests that temperature might affect the rate of mitosis in plant cells Design an experiment to test this hypothesis?
Temperature affects the rate of cell progress that is the mitotic rate to quite some extent. With the increase in temperature(3-25 degrees C) the mitotic cycle rate increases linearly.
Are neurons mitotic?
no
A structure called the mitotic can be seen between the centrioles of animal cells when cells are reproducing?
mitotic spindle
The cloning of cells involves in the process of?
Mitotic cell division. #3 on castlelearning(;
What is a mitotic lesion?
A mitotic lesion is one in which there is an increased rate of mitosis in cells. This can be indicative of cancer where there is abnormal proliferation of cells.
