Spindle fibers extend from the poles and overlap at the spindle equator where some attach to chromosomes to help separate them during cell division.
<h3>What is spindle fiber?</h3>
A single filament that travels from the poles to the center is a spindle fiber. Aster is a single filament as well, but the aster differs in its placement.
<h3>What is spindle equator?</h3>
Chromosome alignment at the spindle equator improves the efficiency of bi-orientation. Chromosome congression, a procedure that moves chromosomes from close to spindle poles to the equator, is necessary for this alignment to take place.
<h3>What is spindle in cell?</h3>
A protein structure called a spindle fiber divides a cell's genetic material.

Explanation:
<em><u>Vitamin D is the sunshine vitamin that has been produced on this earth for more than 500 million years.</u></em>
<em><u>Vitamin D is the sunshine vitamin that has been produced on this earth for more than 500 million years.During exposure to sunlight 7-dehydrocholesterol in the skin absorbs UV B radiation and is converted to previtamin D3 which in turn isomerizes into vitamin D3.</u></em>
The Biopsy researchers take calf muscle biopsies of crew members before and after their stay aboard the International Space Station (ISS). This allows scientists to begin developing an in-space countermeasure exercise program aimed at keeping muscles at their peak performance during long missions in space.<span>

needlestick injuries
An infection that occurs through mucosal surfaces of the eyes, nose, or mouth. This type of transmission can take place through needlestick injuries, human bites, cuts, abrasions, or any break in the skin. What type of transmission involves direct or indirect contact with blood and other body fluids.
