Cell cycle Mitosis/Meiosis

Front

What is the main purpose of mitosis?

Back

To form two identical daughter cells from one parent cell.

Front

What is the significance of crossing over during prophase I of meiosis?

Back

It increases genetic variation by exchanging genetic material between homologous chromosomes.

Front

What phase of the cell cycle is characterized by DNA replication?

Back

S phase (Synthesis phase).

Front

What occurs during metaphase of mitosis?

Back

Chromosomes align at the cell's equatorial plane before being separated.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells have two sets of chromosomes (2n), while haploid cells have one set (n).

Front

What is the role of the G1 phase in the cell cycle?

Back

Cell growth and preparation for DNA synthesis.

Front

What happens during the G2 phase of the cell cycle?

Back

The cell continues to grow and prepares for mitosis.

Front

What is the outcome of meiosis?

Back

Four genetically diverse haploid daughter cells.

Front

What is the function of spindle fibers during mitosis?

Back

To help separate chromosomes and pull them to opposite poles of the cell.

Front

What is the role of checkpoints in the cell cycle?

Back

To ensure that the cell is ready to proceed to the next phase and to prevent errors.
