    2. Mitochondria membrane

    3. DNA

    4. Plasma membrane

    5. Cell enzymes

  2. In spectroscopy nucleotides absorb at 260 nm wavelength. This absorption is due to

    3. Ribose

    4. Histones

    5. Phosphates

  3. Regarding oncogenesis

    1. Topoisomerase II causes break in both strands

    2. P53 is the most common oncogene mutation causing cancer in humans

    3. At G2 − M phase there is loss of inhibitors controlling cell cycle

    4. Decrease in telomerase activity causes antitumor effect

  4. The investigation of choice in acute cholecystitis is

    3. Epinephrine

    4. Glucagon

    5. Insulin

  6. Primary hyperparathyroidism is caused by

    1. Parathyroid hyperplasia

    2. Parathyroid adenoma
