What is the role of the spindle during cell division?

1 pts

volume_mute

The spindle is a critical structure formed during both mitosis and meiosis.

What is its role?

To synthesize new DNA for the daughter cells

To dissolve the cell wall during division

To produce ATP needed for division

To align chromosomes and pull them to opposite poles

During which phase of the cell cycle does DNA replication occur?

1 pts

volume_mute

Before a cell can divide, it must first duplicate all of its genetic material.

What happens to chromosomes at the end of telophase and the beginning of late telophase/cytokinesis?

1 pts

volume_mute

After chromosomes arrive at the poles during telophase, several changes occur as the cell completes division.

Select ALL events that occur at the end of telophase and during cytokinesis.

The spindle apparatus breaks down

Centrioles replicate (in animal cells)

Chromosomes begin to uncoil

Nuclear envelopes reform around each set of chromosomes

Chromosomes condense further

The cytoplasm divides to produce two daughter cells

How do daughter cells produced by meiosis compare to those produced by mitosis?

1 pts

volume_mute

Both mitosis and meiosis start from a diploid parent cell, but their daughter cells differ in important ways.

Select ALL statements that correctly contrast meiotic daughter cells from mitotic daughter cells.

Meiotic daughter cells are haploid (n); mitotic daughter cells are diploid (2n)

Meiotic daughter cells are genetically unique; mitotic daughter cells are genetically identical

Meiosis involves crossover; mitosis does not
