Front

What phase of interphase does DNA replication occur?

Back

S phase

Front

Which stage of mitosis is characterized by the alignment of chromosomes along the equator of the cell?

Back

Metaphase

Front

What is the end result of mitosis in terms of the number of cells and their genetic content?

Back

Two genetically identical diploid cells

Front

What causes cancer tumors?

Back

Rapid cell division

Front

Which chromosomal abnormality can be detected by karyotyping?

Back

Trisomy 21

Front

What is the purpose of mitosis?

Back

To produce two identical daughter cells for growth and repair.

Front

What is meiosis?

Back

A type of cell division that reduces the chromosome number by half, producing four haploid cells.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells have two sets of chromosomes, while haploid cells have one set.

Front

What is the role of spindle fibers during mitosis?

Back

To help separate the chromosomes during cell division.

Front

What happens during prophase of mitosis?

Back

Chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.
