Question

During the G2 phase of interphase, the cell prepares for mitosis and proteins organize themselves into a series of fibers called ____________.

a) Microtubules
b) Centrioles
c) Chromatin
d) Chromosomes
e) Spindle fibers

Answer 1

In the G2 phase of interphase, proteins organize into spindle fibers, which are made up of microtubules critical for mitosis.

Step-by-step explanation:

During the G2 phase of interphase, the cell prepares for mitosis and proteins organize themselves into a series of fibers called spindle fibers.

These are composed of microtubules, which include kinetochore microtubules that attach to the kinetochores of chromosomes, and polar microtubules that help in cell elongation. Astral microtubules are also part of the spindle apparatus, aiding in spindle orientation and the regulation of mitosis.
