Why does DNA flow toward the positive electrode of the gel chamber?

Digiron [165]

Answer:

DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole.

Explanation:

Electrophoresis is a technique that uses differences in electrical charge to separate the molecules in a mixture. DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole. The rate of migration of a molecule depends on two factors, its shape, and its charge-to-mass ratio.

A gel, which is usually made of agarose, polyacrylamide, or a mixture of the two comprises a complex network of pores, through which the DNA molecules must travel to reach the positive electrode. The smaller the DNA molecule, the faster it can migrate through the gel. Gel electrophoresis, therefore, separates DNA molecules according to their size.

arlik [135]

Looking at the two species' DNA would be a good place to start. If there are a number of similarities in their genotypes, then there would be a good chance that the two would also share some type of a common ancestor. This would be evidence that there was some type of selection that took place that necessitated two different species that shared a number of traits and features.

What is genetic equilibrium, and how does it occur (five conditions)?

alexgriva [62]

Five conditions are required in order for a population to remain at Hardy-Weinberg equilibrium: A large breeding population. Random mating. No change in allelic frequency due to mutation.
