Question

the mitotic spindle consists of two types of microtubules: kinetochore microtubules and nonkinetochore microtubules. in animal cells, these two types of microtubules function differently in the stages of mitosis.
complete the sentences by dragging the terms to the appropriate locations. terms may be used once, more than once, or not at all.

1. during prophase, the microtubules of the mitotic spindle.
2. during anaphase, the nonkinetochore microtubulesand move past each other, and the kinetochore microtubules.
3. during telophase, the nonkinetochore microtubules.

Explanation:

• During prophase, microtubules of the mitotic spindle lengthen. This is part of the spindle formation process where microtubules grow to form the structure that will later be involved in chromosome movement.
• During anaphase, non - kinetochore microtubules lengthen and move past each other. Non - kinetochore microtubules (also called polar microtubules) push against each other to elongate the cell and help in the separation of chromosomes to opposite poles.
• During telophase, non - kinetochore microtubules disassemble. As the cell is preparing for cytokinesis and the mitotic spindle is no longer needed in its extended form, these microtubules break down.

Answer:

1. lengthen
2. lengthen; move
3. disassemble
