11) Which of the following descriptions of DNA replication is not common to the

synthesis of both leading and lagging strands?

A) RNA primer is synthesized

B) Helicase continuously unwinds duplex DNA at the replication fork during


C) DNA polymerase III synthesizes DNA

D) DNA ligase repeatedly joins the ends of DNA along growing strand

Correct answer: C     2014 svims

Multiple DNA polymerases take on different roles in the DNA replication process.

In E. coli, DNA Pol III is the polymerase enzyme primarily responsible for DNA

replication. It assembles into a replication complex at the replication fork that exhibits

extremely high processivity, remaining intact for the entire replication cycle.

  • In contrast, DNA Pol I is the enzyme responsible for replacing RNA primers with DNA. DNA Pol I has a 5′ to 3′ exonuclease activity in addition to its polymerase activity, and uses its exonuclease activity to degrade the RNA primers ahead of it as it extends the DNA strand behind it, in a process called nick translation.
    • Pol I is much less processive than Pol III because its primary function in DNA replication is to create many short DNA regions rather than a few very long regions.

Leading strand

  • The leading strand is the strand of nascent DNA which is being synthesized in the same direction as the growing replication fork.
  • A polymerase "reads" the leading strand template and adds complementary nucleotides to the nascent leading strand on a continuous basis.
  • The polymerase involved in leading strand synthesis is DNA polymerase III (DNA Pol III) in prokaryotes and presumably Pol ε in yeasts. In human cells the leading and lagging strands are synthesized by Pol ε and Pol δ, respectively, within the nucleus and Pol γ in the mitochondria.
  • Pol ε can substitute for Pol δ in special circumstances

SJS and > 30% of body surface area in TEN; involvement of 15 to 30% of

body surface area is considered SJS/TEN overlap.



72) All the following conditions cause hypertension except

A) Lead poisoning

B) Acute porphyria

C) Cushing’s syndrome

D) Bartter’s syndrome

Correct answer: D    2014 svims

  • Bartter syndrome and Gitelman syndrome (also called tubular hypomagnesemia-hypokalemia with hypocalciuria) are autosomal recessive disorders with a characteristic set of metabolic abnormalities
  • These include hypokalemia, metabolic alkalosis, hyperreninemia, hyperplasia of the juxtaglomerular apparatus (the source of renin in the kidney), hyperaldosteronism, and, in some patients, hypomagnesemia.
  • The hyperaldosteronism associated with Bartter and Gitelman syndromes is a secondary form of hyperaldosteronism that results from a volume contraction-induced increase in renin. These patients are not hypertensive
  • The tubular defects in sodium chloride transport are almost identical to that seen with chronic ingestion of a loop diuretic (mimicking Bartter syndrome) or a thiazide diuretic (mimicking Gitelman syndrome).
  • The salt wasting that occurs results in the following features common to patients with both disorders


73) Organism responsible for recurrent Mollaret meningitis is

A) Herpes virus type 2

B) Epstein Barr virus

C) Coccidia

D) Herpes virus type 1

Correct answer: A    2014 svims

Mollaret’s meningitis is a recurrent or chronic inflammation of meninges. Since Mollaret meningitis is a recurrent, benign (non-cancerous), aseptic meningitis, it is now referred to as benign recurrent lymphocytic meningitis.

  • Although for a long time, the cause of Mollaret’s meningitis was not known, recent work has associated this problem with herpes simplex viruses, which cause cold sores and genital herpes.
  • Cases of Mollaret’s resulting from Varicella zoster virus infection, diagnosed by PCR, have been documented. In these cases, PCR for herpes simplex was negative. Some patients also report frequent shingles outbreaks.
  • The chickenpox virus is part of the herpes family.
  • CNS epidermoid cysts can give rise to Mollaret’s meningitis especially with surgical manipulation of cyst contents.

74) Indication for cardiac resynchronization in chronic heart failure

A) NYHA class II

B) QRS duration > 120ms

C) Ejection faction > 40%

D) Atrial fibrillation

Correct answer: B    2014 svims

Cardiac resynchronization therapy (CRT) is a relatively new therapy for

patients with symptomatic heart failure resulting from systolic

dysfunction. CRT is achieved by simultaneously pacing both the left

and right ventricles. Biventricular pacing resynchronizes the timing of

global left ventricular depolarization and improves mechanical

contractility and mitral regurgitation.


75) Mechanism of action of sitagliptin

A) DPP IV inhibitor

B) GLP I agonist

C) Inhibit hepatic gluconeogenesis

D) PPAR-gamma receptor agonist

Correct answer: A    2014 svims

Sitagliptin  is an oral antihyperglycemic (antidiabetic drug) of the dipeptidyl

peptidase-4 (DPP-4) inhibitor class. This enzyme-inhibiting drug is used either alone

or in combination with other oral antihyperglycemic agents (such as metformin or a

thiazolidinedione) for treatment of diabetes mellitus type 2 The benefit of this medicine

is its fewer side effects (e.g., less hypoglycemia, less weight gain) in the control of blood

glucose values. While safety is its advantage, efficacy is often challenged as it is often

recommended to be combined with other agents such as metformin.
