Answer:
The DNA will still move towards the positive electrode
Explanation:
Gel electrophoresis is a technique which is used by the molecular biologist to separate the fragments of DNA. In the procedure, a DNA sample of a particular concentration of DNA sample composed of a particular length of DNA is loaded into the samples.
The gel is usually set up with the positive electrode at the bottom and negative at the top which by mistake when placed at the bottom and positive at the top.
The DNA will still move from the DNA wells towards the positive side as the DNA moves in the gel as the DNA posses negative charge due to phosphate groups they have and therefore move towards the positive electrode (opposite charge always).
Thus, the DNA will still move towards the positive electrode is correct.
Let's discuss first about difference between micro- and macro-nutrients. Micronutrients are those which are needed in small quantities and their function is not that vast. But macronutrients are the ones which control all the metabolic cycles of the cell, so they are needed in large quantities. This is the basic difference between the two terms.
Proteins are macro-nutrients because they are needed in large amount, as they are involved in some of the most important functions of our body. For example, proteins act as enzymes, involved in immunity, maintaining homeostasis of the body, etc. That is why they are considered as macronutrients.
Answer:
The heliocentric theory suggest that the sun is the central body of the solar system and perhaps of the universe. Everything else (planets and their satellites, asteroids, comets, etc.) revolves around it. The first evidence of the theory is found in the writings of ancient Greek philosopher-scientists.
