Factor VIII is one of the factors required for natural blood dotting process in human and is located in the X chromosome. A genetic defect in the synthesis of factor VIII results in the disease haemophilia, a sex linked disease

hGH stands for Human Growth Hormone Somatostatin and Somatotropin are human growth hormones which are peptide hormones produced by the pituitary gland. They are produced by DNA recombinant technology and are used to treat growth disorders in children

It is a protein which is most abundant in human milk. It is synthesized by the mammary glands. It binds calcium and zinc ions and possesses bactericidal and antitumour properties

Alpha lactalbumin is a protein composed of 123 amino acids. It is the most abundant protein in human mille

(i) PCR is a very sensitive technique which enables the amplification of desired DNA from a limited amount of DNA template.
(ii) A technique can be also used for amplifications of RNA in which case it is referred to as reverse transcription PCR (RT-PCR). In this process the RNA molecules (mRNA) must be converted to complementary DNA by the enzyme reverse transcriptase (reverse transcription).
(iii) The cDNA then serves as the template for PCR.
(iv) The specificity and sensitivity of PCR is useful for the diagnosis of inherited disorders (genetic, viral; bacterial, diseases).
(v) Hence, it can detect the presence of an infectious organism in the infected patient at an early stage of infection (even before the infectious organism has multiplied into large number).
