Read the passage carefully and answer the given questions.
Recombinant DNA Technology
Asexual reproduction preserves the genetic information, while sexual reproduction permits variation. Traditional hybridization procedures used in plants and animals breeding very often lead to inclusion and multiplication of undesirable genes along with the desired genes. The techniques of genetic engineering, which include creation of recombinant DNA, use of gene cloning and gene transfer, overcome this limitation and allow us to isolate and introduce only one or a set of desirable genes without introducing genes into the target organism.
Which one of the following techniques is used to amplify a specific DNA
sequence?

Which of the following does not show symbiotic association?

Which one of the following genotypes represents a similar skin color?

The rate of formation of new organic matter by consumers in termed as:-

Which one of the following is not practiced in the organic farming?

The function \(f(x)=x^3-3 x\) is :

Amines are reactive in nature, mainly due to difference in electronegativity between Nitrogen and Hydrogen and, due to lone pair of electrons on Nitrogen. Amines behave like nucleophiles and as good lewis bases and there are various reactions to support this. Different degree of amines differ in their reactivity due to steric hinderance and electronic effects. Aromatic amines are less basic due to + R effect,
hence have higher pkb value than aliphatic amines. Basic strength of amines also depends on stability of corresponding conjugate acid in aqueous medium.
'A' compound is treated with Hinsenberg's reagent, subsequent additiom of alkali to it gives a clear solution. Compound ' A ' is:

Which one of the following hormones is produced only during pregnancy?

Ravish rowed 40 km downstream in 2 hrs 30 min and returned to the starting point in 5 hrs . What is the speed of the current ?

For a coil of 5 turns, the magnetic flux varies with time as \( \phi_{B}(t) = (2t^3 - \frac{5}{2}t^2 + t) \), where \( \phi_{B}(t) \) and t are in S.I. units. The induced current at t = 2 s in the coil, if its total resistance is 150 \( \Omega \), is :

Arrange the steps followed during nucleophilic addition on a carbonyl group.
A. \(s p^2\) hybridised carbon of \(>C=O\) group changes to \(s p^3\) hybridised carbon
B. Nucleophile attacks the electrophilic carbon
C. Tetrahedral alkoxide ion is formed
D. Intermediate captures \(H ^{+}\)to give neutral product.
