Mitosis

Front

What is the definition of a chromosome?

Back

A chromosome is a long, thread-like structure made of DNA and proteins that contains genetic information.

Front

What phase comes before Anaphase in mitosis?

Back

The phase that comes before Anaphase is Metaphase.

Front

What is the role of chromatids during mitosis?

Back

Chromatids are the two identical halves of a duplicated chromosome that are separated during mitosis.

Front

How many chromosomes do fruit fly daughter cells have after mitosis?

Back

Fruit fly daughter cells have 8 chromosomes after mitosis.

Front

What is the definition of Prophase in mitosis?

Back

Prophase is the first stage of mitosis where chromosomes condense and become visible, and the nuclear envelope begins to break down.

Front

What happens during Metaphase?

Back

During Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What is the function of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined and where the spindle fibers attach during mitosis.

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is the significance of mitosis?

Back

Mitosis is significant for growth, development, and tissue repair in multicellular organisms.

Front

What is the difference between a chromatid and a chromosome?

Back

A chromatid is one half of a duplicated chromosome, while a chromosome is made up of two sister chromatids joined at the centromere.
