Mitosis Practice Flashcard

Front

What does PMAT stand for in the context of cell division?

Back

PMAT stands for Prophase, Metaphase, Anaphase, and Telophase, which are the stages of mitosis.

Front

What is the centromere?

Back

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

Front

What phase of mitosis is characterized by the condensation of chromatin into visible chromosomes?

Back

Prophase.

Front

What is Interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication and cell growth.

Front

What must be copied before a cell can divide?

Back

DNA must be copied before a cell can divide.

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 occurs during Anaphase?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell.

Front

What is Telophase?

Back

Telophase is the final stage of mitosis where the chromosomes de-condense, and nuclear membranes reform around each set of chromosomes.

Front

What is the role of spindle fibers in mitosis?

Back

Spindle fibers help separate the chromosomes during cell division by attaching to the centromeres and pulling the chromatids apart.

Front

What is the difference between chromatin and chromosomes?

Back

Chromatin is the loose form of DNA found in the nucleus during interphase, while chromosomes are the tightly coiled structures formed during mitosis.
