Assertion : Cornea is considered as an immunologically privileged site. Reason : A transplanted cornea is rarely rejected.

The immunological protein particles which restrict viral reinfection by not joining viral mRNA to ribosome of host cells, once animals have been infected by virus, is

A : Recombinant DNA technologies process has been less effective in therapeutic drug production. R : Recombinant therapeutics induce unwanted immunological responses.

Assertion: The recombinant therapeutics do not induce unwanted immunological responses. Reason :About 30 recombinant therapetics have been approved for human use world -wide

[A] : The plasmalemmas of animals cells typically have the oligosaccharide chains of their glycolipids and exposed freely on their surfaces . [R] : These play important roles in immunological responses , in cell-cell adhesion and identification of cell surface changes.

Assertion : In placental mammals the placenta is connected to the embryo by the umblical cord and has an essential role in the immunological protection of the embryo . Reason : In mammals foetal components of the placenta derive initially from the chondroblast connected with embryonic derive initially from he chondroblast connected with embryonic blood stream either through its contact with the yolk sac.
