AP Bio 13.3 and 4 Flashcard

Front

What is required to view and analyze human chromosomes in a dividing cell?

Back

A DNA stain and a light microscope are required.

Front

What occurs when homologous chromosomes crossover?

Back

Specific proteins break the two strands and re-join them with their homologs.

Front

When does a cell divide to produce genetically different daughter cells?

Back

This occurs during meiosis I.

Front

What happens at the conclusion of meiosis I?

Back

Homologous chromosomes are separated.

Front

In which process does independent assortment of chromosomes occur?

Back

Independent assortment occurs during meiosis I.

Front

What is the role of a DNA stain in chromosome analysis?

Back

A DNA stain helps visualize chromosomes under a light microscope.

Front

What is the difference between mitosis and meiosis in terms of genetic variation?

Back

Mitosis produces genetically identical cells, while meiosis produces genetically diverse cells.

Front

What is the significance of crossing over in meiosis?

Back

Crossing over increases genetic diversity by exchanging DNA between homologous chromosomes.

Front

Define homologous chromosomes.

Back

Homologous chromosomes are pairs of chromosomes that have the same structure and gene sequence, one inherited from each parent.

Front

What is the outcome of meiosis II?

Back

Meiosis II results in four genetically diverse haploid daughter cells.
