Answer:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
The correct answer is:
(A) In metaphase I, tetrad sets of homologous chromosomes stay together as they line up along the center of the cell.
Explanation:
In meiosis, homologous chromosomes pair with each other (i.e., they form tetrads) and crossing-over occur. In mitosis, not of these things occur. In metaphase I of meiosis, tetrads follow on the metaphase plate. In mitosis, there is only one state and it creates two daughter cells
