conclusion.

Which one of the following statements is not correct regarding the DNA?

Read the passage carefully and give the answers to the question :
India was amongst the first countries in the world to initiate action plans and programmes at a national level to attain total reproductive health as a social goal.
These programmes called 'family planning' were initiated in 1951 and were periodically assessed over the past decades. Improved programmes covering wider reproduction-related areas are currently in operation. Creating awareness among the people about various reproduction-related aspects and providing facilities and support for building up a reproductively healthy society are the major tasks under these programmes.

In 1997, the first transgenic cow, Rosie, produced human protein-enriched milk. The milk contained the _________ and was nutritionally a more balanced product for human babies than natural cow-milk.

For which of the following disease, the transgenic animal model has not been developed ?

Pentan-2-one and pentan-3-one can be distinguished by

Consider the two complex ions \(\text{[CoF}_6]^{3-}\) and \(\text{[Co(C}_2\text{O}_4)_3]^{3-}\), which of the following statement (s) is/are false :
(A) Both are octahedral.
(B) \(\text{[Co(C}_2\text{O}_4)_3]^{3-}\) is diamagnetic, while \(\text{[CoF}_6]^{3-}\) is paramagnetic.
(C) Both are outer orbital complexes.
(D) In both the complexes the central metal is in the same oxidation state.
Choose the correct answer from the options given below :

Transition metals form a large number of complexes or coordination compounds in which the metal atoms are bound to a number of anions or neutral molecules. The valence bond theory explain the formation, magnetic behaviour and geometrical shapes while the crystal field theory explains the effect of different crystal fields on the degeneracy of d-orbitals energies of the central metal atom/ion. This provides for the quantitative estimation of orbital separation energies, magnetic moments and spectral and stability parameters.
Two complexes of nickel have same geometry but different magnetic behaviour are:
(A) \(\text{[Ni(CN)}_4]^{2-}\)
(B) \(\text{[Ni(CO)}_4]\)
(C) \(\text{[NiCl}_4]^{2-}\)
(D) \(\text{[Ni(NH}_3)_6]^{2+}\)
