Question

Dynamic instability is:

A. the ability of a microtubule to shrink rapidly during mitosis.
B. the ability of a microtubule to grow rapidly during meiosis.
C. the ability of a microtubule to switch back and forth between polymerization and
depolymerization.
D. the ability of a microtubule to switch polarity back and forth between a positive and
negative charge.

Answer 1

Dynamic instability is the ability of a microtubule to switch between polymerization and depolymerization. Microtubules are hollow tubes made up of alpha-tubulin and beta-tubulin dimers. They play a vital role in cell division and can disassemble and reform rapidly.

Step-by-step explanation:

Dynamic instability refers to the ability of a microtubule to switch back and forth between polymerization and depolymerization. Microtubules are small hollow tubes made up of polymerized dimers of alpha-tubulin and beta-tubulin. They play a crucial role in cell division, as they set the paths along which the genetic material is pulled. Microtubules can also disassemble and reform quickly.
