The resistance of a potentiometer wire of length 4 m is \( 10 \ \Omega \).
A resistance box and a 2 V accumulator are connected in series with it.
What resistance should be introduced in the box to have a potential drop of \( 1 \ \mu\text{V/mm} \) along the potentiometer wire?

The number of free electrons per 100 mm of ordinary copper wire is 2 \(\times 10^{21}\). The average drift speed of electrons is 0.25 mm/s. The amount of current flowing would be : (e = 1.6 \(\times 10^{-19}\) C)

Keeping the voltage of the charging source constant, the separation between the plates of the capacitor is decreased by 10%. The percentage change in the energy stored in the capacitor will be:

Read the Passage carefully and answer the the questions
Insulin consists of two short polypeptide chains : chain A and chain B, that are linked together by disulphide bridges. The first clinical gene therapy was given in 1990 to a 4-year old girl with adenosine deaminase (ADA) deficiency. This enzyme is crucial for the immune system to function. Recombinant DNA technology, Polymerase Chain Reaction (PCR) and Enzyme Linked Immuno-sorbent Assay (ELISA) are some of the techniques that serve the purpose of early diagnosis of diseases. Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (or genes) which codes for a particular product such as human protein (α-1-antitrypsin) used to treat emphysema. Biopiracy is the term used to refer to the use of bio-resources by multinational companies and other organisations without proper authorisation from the countries and people concerned without compensatory payment.
In early diagnosis of disease, the principle of antigen-antibody interaction operates in -

(A) \(P(A \cap B)=0\)
(B) \(P(A \cup B)=1-P\left(A^{\prime}\right) P\left(B^{\prime}\right)\)
(C) \(P(A \cup B)=P(A) P(B)\)
(D) \(P(A \cap B)=P(A) P(B)\)
