What are chromatids?

Back

Chromatids are the two identical halves of a duplicated chromosome, which are joined together by a centromere.

Front

When does the segregation of homologous chromosomes occur during meiosis?

Back

Segregation of homologous chromosomes occurs between stages 1 and 2 of meiosis.

Front

What is a mutation?

Back

A mutation is a change in DNA that can have various effects on an organism.

Front

What stages of the cell cycle are represented by interphase and mitosis?

Back

Arrow 1 represents interphase, and Arrow 2 represents mitosis.

Front

What is the stage of mitosis where chromosomes are pulled apart?

Back

Anaphase is the stage of mitosis where sister chromatids are separated and pulled to opposite poles of the cell.

Front

What is the role of centrioles in cell division?

Back

Centrioles help organize the mitotic spindle during cell division.

Front

What occurs during cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parental cell is divided into two daughter cells.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is the function of the centromere?

Back

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

Front

What happens during prophase of mitosis?

Back

During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.
