Identify the correct combination of salient features of the genetic code.
(A) AUG has dual functions as it codes for methionine (met), and also act as initiator codon.
(B) Some amino acids are coded by more than one codon, hence the code is degenerate.
(C) UAA, UAG, UGG are stop terminator codons.
(D) The codon is read in mRNA in a continuous fashion and there are no punctuations.

Answer the question on the basis of passage given below:
In the periodic table, the d-block contains the elements of group \(3\) to \(12\). The d-orbitals are progressively filled in each of the four long periods. The elements of d block referred as transition metals have partly filled d orbitals and exhibit certain characteristic properties such as variety of oxidation states, formation of coloured ions, act as catalyst and show paramagnetic behaviour.
The two inner transition metals series \(4f\) and \(5f\) are known as Lanthanoids and Actinoids respectively. The lanthanoids resemble one another more closely as compared to ordinary transition elements in any series.
In context of the Lanthanoids, which of the following statements is/are NOT correct?
A. There is a gradual decrease in the radii of the members with increasing atomic number in the series
B. Availability of \(4f\) electrons results in the formation of compounds in \(+4\) oxidation state for all the members of the series
C. Because of similar properties, the separation of lanthanoids is not easy
D. \(La(OH)_3\) is least basic among hydroxides of lanthanoids
E. Ce can act as an oxidising agent

How much calcium will be obtained when 4 Faradays of electricity is passed through molten CaCl2?

A charge q is moving with velocity \( \vec{v} \) in the presence of both electric field \( \vec{E} \) and magnetic field \( \vec{B} \). If velocity (\( \vec{v} \)), electric field (\( \vec{E} \)) and the magnetic field (\( \vec{B} \)) are mutually perpendicular. The charge will pass through the field undeflected if :

The concentration dependence of the rate of a reaction is called the differential rate equation. It is not always convenient to determine the instantaneous rate, as it is measured by calculating the slope of the tangent at point 't' in the concentration vs time plot. This makes it difficult to determine the rate and hence the order of the reaction. This difficulty is overcome by integrating the differential rate equation. This integrated rate equation gives a direct relation between concentrations at different times and the rate constant. The integrated rate equations are different for the reactions having different reaction orders.
For an integrated first order reaction, a straight line graph is plotted. The incorrect co-ordinates and resulting slope of the graph are

For an endothermic reaction, energy of activation is \(E_a\) and enthalpy of reaction is \(\Delta H\)
(both of these are in \(kJ'\) mol\(^{-1}\)), minimum value of \(E_a\) will be :
