Looking through a light microscope at a cell undergoing division, you see that the condensed chromosomes have lined up along the midline of the cell. the homologous pairs are not joined in tetrads. each chromosome takes its own place in line, independent of its homolog. you are witnessing

Mitotic metaphase or metaphase II of meiosis

Explanation:

Metaphase in mitosis and metaphase II of meiosis II include alignment of chromosomes along the equator of the cell with help of spindle apparatus. Here, each chromosome has two sister chromatids.

Metaphase I of meiosis I includes alignment of homologous pairs along the equator of the cell. Since the observed cell have individuals chromosomes aligned along the mid line of the cell, it is metaphase of mitosis or metaphase II of meiosis.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
