The time period Tumor markers can also discuss with proteins which can be made by both healthy cells and cancer cells in the frame. it could also talk to mutations, modifications, or styles in a tumor DNA. Tumor markers are also known as biomarkers. docs might also use tumor marker exams to study when you have cancer.
Protein molecular weight markers, from time to time known as protein requirements or protein ladders, are used to estimate the molecular weight of proteins of hobby and to monitor the development of electrophoretic separation or transfer in Western blotting.

Answer:
Adjacent to the yolk sac
Explanation:
Chorionic villi are microscopic and fingerlike projections found near the placenta which contain capillaries, increase surface area of blood that allow blood to flow and transfer nutrients from the mother to the fetus. The chorionic villi is adjacent to the yolk sac because it developed from the yolk sac, villi can extend and contact maternal blood vessels thereby nourishing the embryo and transfering nutrients from the mother to the fetus.
Answer:
Antigens, and epitopes.
Explanation:
Antigen is known as a substances which is capable of the causes an immune response in the body, and specifically activating white blood cells which are known as body's infection fighting cells. In general antigens are two types:
1) Foreign antigens or heteroantigens.
2) Auto-antigens or self antigens.
Epitopes are the part of an antigen which is recognized with the help of immune system, specifically by B cells, T cells, and antibodies. They are also called as antigenic determinants. The epitope is defined as the specific part of the antigen where an antibody binds.
