Answer:

The correct answer would be A) DNA.

Electrophoresis or gel electrophoresis is a technique used to separate the charged particles such as DNA, RNA, and proteins on the basis of their size.

Under this technique, the charged particles are allowed to move under a uniform electric field.

The gel or gel pores act as a sieve through which the charged particles move and thus, the smallest fragment reaches the farthest end and in the smallest interval of time.

For example, DNA is a negatively charged particle which moves from cathode to anode and DNA fragments are separated according to their size.

Bogdan [553]

Answer:

The answer to the question: Class II MHC proteins are found on which of the following cell types, would be: on macrophages and lymphocytes, particularly T-Cells.

Explanation:

MHC, or Major histocompatibility complex, is a very important part of the immune response that the body gives against an invading pathogen, or other foreign substances. There are three types in the human body, Class I, Class II and Class III and each of them will play a role on the cellular membrance of different types of cells and mediate different types of responses. In the human body, this histocompatibility complex is best known as HLA, or human leukocyte antigen, and it will ensure the recognition, or non-recognition of substances, tissues, and other organisms, by the human immune system. Class II, as mentioned before, are most usually found on the immune cells macrophages and lymphocytes, and they are the ones responsible for presenting antigens to these proteinic antibodies so that the immune cells can initiate a proper immune response.

To extract energy from carbohydrates, glucose is oxidized through several metabolic processes, resulting in end products of carb
BlackZzzverrR [31]

Answer:the item that has steps involved in glucose oxidation in an aerobic environment is ATP.

CH12O6 + 6O2 + 36Pi^-1 + 36ADP^3- + 35H^+ = 6CO2 + 36ATP^4- + 42H2O

Explanation:

Aerobic oxidation of glucose is coupled to the synthesis of as many as 36 molecules of ATP: Glycolysis, the initial stage of glucose metabolism, takes place in the cytosol and does not involve molecular O2. It produces a small amount of ATP and the three-carbon compound pyruvate.
