A molecule that can act as the genetic material must fulfill all the mentioned criteria except one which is incorrect.

In 1953, S.L. Miller performed an experiment where he observed the fraction of amino acids. The precursors

Read the given paragraph carefully and answer the following questions:
Since the DNA is enclosed within the membranes, we have to break the cell open to release DNA along with other macromolecules such as RNA, proteins, polysaccharides and also lipids. This can be achieved by treating the bacterial cells/plant or animal tissue with enzymes such as lysozyme (bacteria), cellulase (plant cells), chitinase (fungus). There are some basic steps in genetically modifying an organism (i) identification of DNA with desirable genes; (ii) introduction of the identified DNA into the host; (iii) maintenance of introduced DNA in the host and transfer of the DNA to its progeny. Agrobacterium tumifaciens, a pathogen of several dicot plants is able to deliver a piece of DNA known as 'T-DNA' to transform normal plant cells into a tumor and direct these tumor cells to produce the chemicals required by the pathogen. Other molecules can be removed by appropriate treatments and purified DNA ultimately precipitates out after the addition of chilled ethanol. Selection of recombinants due to inactivation of antibiotics is a cumbersome procedure because it requires simultaneous plating on two plates having different antibiotics. Therefore, alternative selectable markers have been developed which differentiate recombinants from non-recombinants on the basis of their ability to produce colour in the presence of a chromogenic substrate. In this, a recombinant DNA is inserted within the coding sequence of an enzyme, ß'-galactosidase. This results into inactivation of the gene for synthesis of this enzyme, which is referred to as insertional inactivation.
Agrobacterium tumefaciens, a pathogen of several dicot plants, is able to deliver a piece of DNA known as:

The self-inductance (L) of a long solenoid on doubling its number of turns and length, keeping other factors constant, will become

The solution of the differential equation \(\frac{d y}{d x}-\frac{y}{x}=2 \log _e x\)

Which one of the following events does not occur during gene regulation in eukaryotes?

A pair of dice is thrown, getting a total of 7 is considered a success. Then the probability of success in a single throw is:

A potentiometer wire has a uniform potential gradient. The specific resistance of the material of the wire is \(10^{-7} \text{ ohm-m}\), the current passing through it is 0.1 A and its cross-sectional area is \(10^{-6} \text{ m}^2\). What is the value of the potential gradient?
