The nitrogenous bases Adenine form two hydrogen bonds with thymine and the cytosine form three hydrogen bonds with the guanine. Simply, A combines with T and G combines with the C. It is often called as a complementary base pairing because of each base pair bonds only with its specific complementary base partner in a DNA molecule.
Its conversion of pyruvate, a process where each molecule loses one carbon atom with the release of carbon dioxide
During T cell maturation, the t cells must pass two tests. first, immature t cells that can recognize MHC molecules are Selection. Second, immature t cells that recognize and bind to molecules normally found in the body are Activation.
Selection is the first test that T cells must pass. During this process, immature T cells that can recognize MHC molecules are selected. MHC molecules are found on the surface of cells and are involved in antigen presentation. When T cells come into contact with MHC molecules, they are able to recognize the molecules and begin the process of selection. During selection, the T cells that recognize MHC molecules are chosen over those that do not. This helps ensure that the cells that are selected are those that can properly respond to antigens.
The second test that T cells must pass is activation. During activation, T cells that recognize and bind to molecules normally found in the body are selected. These molecules are called self-antigens and can include proteins, carbohydrates, and lipids. When T cells come into contact with self-antigens, they are able to recognize the molecules and begin the process of activation. During activation, the T cells that recognize self-antigens are chosen over those that do not. This helps ensure that the cells that are selected are those that will not attack the body’s own cells.

That would be myology. Myology is the study of the muscular system, wlong with its nature, structure, functions and diseases. It mainly deals with the three types of muscles found in the human body: skeletal muscles, smooth muscles, and cardiac muscles. Muscles are also categorized depending on whether or not they are voluntary or involuntary. Myology is concerned with the study of all this and much more.
