At the end of prophase, spindle fibers form among the chromosomes, and the kinetochore of each chromatid becomes attached to which specific structure, formed by a spindle fiber?

Chromosomal Microtubule

Explanation:

Chromosomal microtubule are tiny hollow structure that appear tube-like under the microscope which are primarily made from cytoskeleton's proteins and beta tubulin. They are polar molecules formed by spindle fiber with fast growing positively charged end and slow-growing negative ends.

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
