Question

the diagram shows phases of the cell cycle in animal cells.
what happens during anaphase? select all that apply.
the spindle fibers pull sister chromatids apart.
chromosomes unravel into chromatin.
the separated chromosomes move toward opposite poles of the cell.
new nuclear envelopes form, creating two daughter nuclei.

Explanation:

• During anaphase, spindle fibers pull sister chromatids apart. This is a key event in anaphase as it ensures the equal distribution of genetic material.
• The separated chromosomes then move toward opposite poles of the cell. This movement is facilitated by the spindle fibers and is crucial for the formation of two genetically identical daughter cells.
• Chromosomes unraveling into chromatin occurs in telophase, not anaphase.
• New nuclear envelopes forming to create two daughter nuclei also happens in telophase.

Answer:

• The spindle fibers pull sister chromatids apart.
• The separated chromosomes move toward opposite poles of the cell.
