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 produce ATP needed for division

To synthesize new DNA for the daughter cells

To dissolve the cell wall during 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.

During which phase does DNA replication take place?

Interphase

Telophase

Prophase

Metaphase

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.

Chromosomes begin to uncoil

The spindle apparatus breaks down

Centrioles replicate (in animal cells)

Nuclear envelopes reform around each set of chromosomes

The cytoplasm divides to produce two daughter cells

Chromosomes condense further

In meiosis, what happens during the first meiotic division?

1 pts

The first meiotic division is fundamentally different from mitosis and from the second meiotic division.

What specifically separates during the first meiotic division?

Sister chromatids separate from each other

The nuclear envelope divides in two

Homologous chromosome pairs separate into two cells

DNA replication occurs for the first time

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.

Both types of daughter cells are identical to each other and to the parent cell

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

Meiosis produces four cells; mitosis produces two

Meiosis involves crossover; mitosis does not

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