Spindle fibres are structures that form during cell division to help separate chromosomes.

Front

What is a diploid cell?

Back

A diploid cell is a cell that contains two sets of chromosomes, one from each parent.

Front

How many chromosomes does each skin cell in a kangaroo have?

Back

Front

What is the role of the centromere in a chromosome?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together.

Front

What is the process of mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is the difference between haploid and diploid cells?

Back

Haploid cells have one set of chromosomes, while diploid cells have two sets.

Front

What happens to the number of chromosomes during mitosis?

Back

The number of chromosomes remains the same during mitosis; each daughter cell has the same number as the parent cell.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid at the centromere.
