Gel electrophoresis is a method of genetic analysis which involves seperating segments of DNA based on their size and charge.

It involves cutting DNA with various enzymes, then placing the DNA in an agarose gel. An electrical current is then run through the gel. Because DNA is a polar molecule the DNA segments will travel through the agarose cell as the current is applied. Larger fragments will travel shorter distances than shorter fragments. Two plates with 2 different DNA samples will be conducted and the orientation of the DNA strands will be used to make an analysis by comparing the 2 plates.

The diagram shows the process of meiosis. How many divisions are required to decrease chromosome numbers and produce gametes?
Tresset [83]

The right answer is 2 divisions.

Meiosis follows the replication of DNA from a reproductive cell (male or female). It allows the passage of a so-called diploid mother cell to 2n chromosome homologous chromosomes to 4 single-chromosome haploid daughter cells. For that it must pass by two successive divisions, the first division is reductionelle generating two diploid cells with n chromosomes. the second division is equational giving 4 haploid cells to n chromosomes from the two preceding cells.
