<span>The most crucial principle of ELISA (enzyme-linked immunosorbent assay) is a highly specific antibody-antigen interaction.</span>
ELISA is a biochemical technique used to detect the presence of an antibody or an antigen in the biological sample. Simply described, in an ELISA, an antigen is immobilized on a solid surface and then a specific antibody is applied over the surface so that it can bind to the antigen. The antibody is usually linked to an enzyme, and in the final step, a substrate for that enzyme is added. The enzyme can convert it to some detectable signal, most commonly a color change. <span>Medical usage of ELISA is in the diagnosis of HIV infection, pregnancy tests, measurement of cytokines…</span>
DNA, Deoxyribonucleic acid. DNA is the empirical proof of God.
DNA can never be created naturalistically and is absolutely uniquely structured:
1. DNA contains multiple levels of coded organically constructed information that controls all cellular functions and no natural process is capable of creating or coding.
2. The amino acids that provide the coding fo the genetic information are homochiral. The few, not all, amino acids that can form naturally are not symmetric and are either left-handed or right-handed, called racemic. All amino acids in DNA, RNA, proteins, enzymes, ribosomes and other cellular assemblies are left-handed, 100%. No right-handed amino acid can function within DNA. Nature may produce a partial list of racemic amino acids, but cannot produce homochiral amino acids, again, only produced within a cell.
3. Phosphate penta-sugars provide the overall dual backplane physical structure to allow the amino acids to be affixed and are all right-handed homochiral, not produced in nature and exclusively right-handed.
<span>Cancerous tumors are divided into broad groups on the basis of the particular type of tissue from which the tumor cells arise. this is called histogenesis.
</span><span>Tumors are of different types, some are cancerous and some are benign (non-cancerous). In a disease of cancer, there is an abnormal cell growth. It is characterized as out of control cell growth.</span>
Answer:
HAHA Don't say like that dog's are best and the reason if they are because that makes sense there are animals and we r humans
somtimes humans are also idiots (no offence)
Well Have a Great day !
Answer:
Comparative embryology is one of the main lines of evidence in support of evolution. In comparative embryology, the anatomy of embryos from different species are compared through the embryos development. Similarities between different species indicate that we all came from a common ancestor.
Explanation:
