Multiple Choice

What is the correct order of mitosis?

• prophase, metaphase, anaphase, telophase

• metaphase, anaphase, telophase, prophase

• Anaphase, telophase, Prophase, metaphase

• anaphase, telophase prophase, metaphase

Multiple Choice

Haploid cells are sex cells, true or false?

• True

• False

Multiple Choice

Which of these is a centrosome?

• a cell or an organism containing two copies of each chromosome. E.g. most body cells.

• two centrioles forming a T shape at the poles of the cell where the spindle grows from.

• the microtubules that pull the chromosomes towards the centrosomes.

• the point on a bivalent where the spindle attaches to the pair of homologous sister chromatids.

Multiple Choice

Which of these is a spindle?

• a cell or an organism containing two copies of each chromosome. E.g. most body cells.

• two centrioles forming a T shape at the poles of the cell where the spindle grows from.

• the microtubules that pull the chromosomes towards the centrosomes.

• the point on a bivalent where the spindle attaches to the pair of homologous sister chromatids.

Multiple Choice

Which of these is a centromere?

• a cell or an organism containing two copies of each chromosome. E.g. most body cells.

• two centrioles forming a T shape at the poles of the cell where the spindle grows from.

• the microtubules that pull the chromosomes towards the centrosomes.

• the point on a bivalent where the spindle attaches to the pair of homologous sister chromatids.

Multiple Choice

Which is interphase?

• The membrane around the nucleus breaks down.

• The cytoplasm of the cell is separated as a cell membrane divides the cell into two daughter cells.

• Each of the chromosome X-shapes splits to form two single chromosomes. The single chromosomes move away from each other.

• The single chromosomes arrive at opposite ends of the cell. The membranes around each nucleus start to form again.

• The DNA in the cell is copied (making X-shapes, each containing a chromosome and its copy). Sub-cellular parts (such as mitochondria) are also copied.

Multiple Choice

Which is prophase?

• The membrane around the nucleus breaks down.

• The cytoplasm of the cell is separated as a cell membrane divides the cell into two daughter cells.

• Each of the chromosome X-shapes splits to form two single chromosomes. The single chromosomes move away from each other.

• The single chromosomes arrive at opposite ends of the cell. The membranes around each nucleus start to form again.

• The DNA in the cell is copied (making X-shapes, each containing a chromosome and its copy). Sub-cellular parts (such as mitochondria) are also copied.

Multiple Choice

Which is metaphase?

• The membrane around the nucleus breaks down.

• The cytoplasm of the cell is separated as a cell membrane divides the cell into two daughter cells.

• Each of the chromosome X-shapes splits to form two single chromosomes. The single chromosomes move away from each other.

• The single chromosomes arrive at opposite ends of the cell. The membranes around each nucleus start to form again.

• The chromosomes line up in the middle of the cell.

Multiple Choice

Which is anaphase?

• The membrane around the nucleus breaks down.

• The cytoplasm of the cell is separated as a cell membrane divides the cell into two daughter cells.

• Each of the chromosome X-shapes splits to form two single chromosomes. The single chromosomes move away from each other.

• The single chromosomes arrive at opposite ends of the cell. The membranes around each nucleus start to form again.

• The chromosomes line up in the middle of the cell.

Multiple Choice

Which is telophase?

• The membrane around the nucleus breaks down.

• The cytoplasm of the cell is separated as a cell membrane divides the cell into two daughter cells.

• Each of the chromosome X-shapes splits to form two single chromosomes. The single chromosomes move away from each other.

• The single chromosomes arrive at opposite ends of the cell. The membranes around each nucleus start to form again.

• The chromosomes line up in the middle of the cell.

Multiple Choice

Which is cytokinesis?

• The membrane around the nucleus breaks down.

• The cytoplasm of the cell is separated as a cell membrane divides the cell into two daughter cells.

• Each of the chromosome X-shapes splits to form two single chromosomes. The single chromosomes move away from each other.

• The single chromosomes arrive at opposite ends of the cell. The membranes around each nucleus start to form again.

• The chromosomes line up in the middle of the cell.
