    Statements related to human insulin are given below. Which statement(s) is/are correct about genetically engineered insulin? (a) Pro-hormone insulin contains extra stretch of C-peptide (b) A-peptide and B-peptide chains of insulin were produced separately in E.coli, extracted and combined by creating disulphide bond between them (c) Insulin used for treating diabetes was extracted from cattle and pigs (d) Pro-hormone insulin needs to be processed for converting into a mature and functional hormone (e) Some patients develop allergic reactions to foreign insulin Choose the most appropriate answer from the options given below:
    1. Option A: (c), (d) and (e) only
    2. Option B: (a), (b) and (c) only
    3. Option C: (b) only
    4. Option D: (c) and (d) only
    Show answer & explanation

    Correct answer: (C) (b) only

    Explanation

    In recombinant insulin production, A and B chains are produced separately in E. coli and combined by disulphide bonds. Statements (a), (c), (d), and (e) relate to insulin biology/history but not specifically genetically engineered insulin.

    Chemical Coordination and IntegrationZoologyHard
    Which of the following are not the effects of Parathyroid hormone? (a) Stimulates the process of bone resorption (b) Decreases Ca²⁺ level in blood (c) Reabsorption of Ca²⁺ by renal tubules (d) Decreases the absorption of Ca²⁺ from digested food (e) Increases metabolism of carbohydrates Choose the most appropriate answer from the options given below:
    1. Option A: (b) and (c) only
    2. Option B: (a) and (c) only
    3. Option C: (b), (d) and (e) only
    4. Option D: (a) and (e) only
    Show answer & explanation

    Correct answer: (C) (b), (d) and (e) only

    Explanation

    Parathyroid hormone increases blood calcium levels, promotes renal reabsorption of Ca²⁺, and enhances intestinal absorption indirectly via calcitriol. It does not decrease blood calcium, reduce intestinal absorption, or regulate carbohydrate metabolism.

    Molecular Basis of InheritanceZoologyHard
    Ten E.coli cells with ¹⁵N-dsDNA are incubated in medium containing ¹⁴N nucleotide. After 60 minutes, how many E.coli cells will have DNA totally free from ¹⁵N?
    1. Option A: 80 cells
    2. Option B: 20 cells
    3. Option C: 40 cells
    4. Option D: 60 cells

  92. Question 92 (NEET 2022, Q194)

    Neural Control and CoordinationZoologyMedium
    Select the incorrect statement regarding synapses:
    1. Option A: Impulse transmission across a chemical synapse is always faster than that across an electrical synapse
    2. Option B: The membranes of presynaptic and postsynaptic neurons are in close proximity in an electrical synapse
    3. Option C: Electrical current can flow directly from one neuron into the other across the electrical synapse
    4. Option D: Chemical synapses use neurotransmitters
    Show answer & explanation

    Correct answer: (A) Impulse transmission across a chemical synapse is always faster than that across an electrical synapse

    Explanation

    Electrical synapses are faster because ions pass directly between cells. Chemical synapses involve neurotransmitter release and synaptic delay.

In the light of the above statements, choose the most appropriate answer from the options given below:
    1. Option A: Statement I is incorrect but Statement II is correct
    2. Option B: Both Statement I and Statement II are correct
