Spindle Apparatus: The spindle apparatus (also known as the mitotic spindle) is a system of microtubules that functions to move chromosomes during each of the stages of mitosis. Answer and Explanation: Learn more about this topic: Mitotic Spindle | Definition, Formation & Function ...
These systems are complex and comprised of many different components, as shown by the lacrimal apparatus.Answer and Explanation: Lacrimal apparatus refers to the various parts of the eye associated with tear secretion. The lacrimal gland is located at the roof of the eye. It...Become a member...
The generally accepted name 'plasmodesmos' was given by STRASBURGER (1901). Plasmodesmata are protoplasmic connections between cells which originated from a common mother cell by cell division. They are formed by inclusion of either microtubular elements from the spindle apparatus or of elements from...
What is the bell jar apparatus?Science Demonstrations:Because it is frequently difficult to directly observe specific phenomena in science, models are developed that replicate the phenomena. In this way, observations and testing can be done in a laboratory that would otherwise require highly ...
Many cells disassemble and re-arrange their cytoskeleton (microtubules, microfilaments and intermediate filaments) to form the mitotic spindle and contractile ring, which are necessary to drive chromosomal segregation and cytokinesis during cell cycle [[98], [99], [100]], not unlike fetal or neonat...
the car. If you would recall that power is the rate of doing work and work is the product of the force acting parallel to the body and the resulting displacement. Torque is the measure of the capacity of the engine to turn the rotating parts of the car while power is the measure of ...
thereby creating identical nuclei. This is accomplished by opposing microtubules of the spindle apparatus playing a sort of tug-of-war contest, until each is applying sufficient tension to hold in place the specific chromosome each microtubule is handling. This does not happen for all 46 chromosomes...
A centrosome is an organelle that organizes microtubules in animal cells. The centrosome duplicates before cell division to help form the spindle apparatus. 10 Centromere Centromeres are pivotal in maintaining genetic stability across generations. Faulty centromeres can lead to chromosome missegregation an...
They play a crucial role in cell division by forming the spindle apparatus, which is essential for moving chromosomes during mitosis. On the other hand, the centromere is a specific region on a chromosome that appears as a constriction, and it's where the kinetochore forms, which is critical...
Nondisjunction occurs when some aspect of thespindleassembly checkpoint (SAC) fails. The SAC is a molecular complex that holds a cell in anaphase until all of the chromosomes are aligned on the spindle apparatus. Once alignment is confirmed, SAC stops inhibitinganaphasepromoting complex (APC), so ...
