• neoplastic transformation

• No change

• differentiation

The part of the embryo from which the ectoderm, mesoderm, and endoderm are formed in chick is known as

• primitive streak

• hypoblast

• epiblast

• cytotrophoblast

Gram-negative bacteria, Klebsiella pneumoniae, upon infecting humans, results in severe septic shock after a few hours of infection. Which of the following is not true for this type of infection?

• Cell wall endotoxins cause overproduction of cytokines

• Septic shock can be treated by anti-TNFα antibodies.

• Recombinant bacterial proteins can be used for the treatment of septic shock.

• Recombinant TNFα receptor antagonists can be used for the treatment of septic shock.

Which of the following is NOT associated with insulin action?

Bacteriophage T4 infects E. coli and injects its DNA inside the cell. The transcription of viral genes occurs in three stages: immediate-early, early, and late. All the promoters on the viral genome are available, but the control takes place at the level of
