mitosis and meiosis

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells, each with half the number of chromosomes of the parent cell.

Front

What is the synaptonemal complex?

Back

The synaptonemal complex is a protein structure that forms between homologous chromosomes during meiosis, facilitating the pairing and recombination of genetic material.

Front

How many daughter cells are produced by mitosis?

Back

Mitosis produces 2 daughter cells.

Front

How many daughter cells are produced by meiosis?

Back

Meiosis produces 4 daughter cells.

Front

What is the normal diploid number of chromosomes in humans?

Back

The normal diploid number of chromosomes in humans is 46 (23 pairs).

Front

What phase comes before anaphase in mitosis?

Back

The phase that comes before anaphase in mitosis is metaphase.

Front

What is the role of centromeres during cell division?

Back

Centromeres are the regions of chromosomes that link sister chromatids together and are essential for the proper segregation of chromosomes during cell division.

Front

What happens during prophase of mitosis?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

Front

What is the difference between homologous chromosomes and sister chromatids?

Back

Homologous chromosomes are pairs of chromosomes (one from each parent) that have the same genes but may have different alleles, while sister chromatids are identical copies of a single chromosome connected at the centromere.
