This is mainly based on Hard - Soft acid base theory.

The reaction is maintained at a low temperature with slow addition of the HNO3/H2SO4 mixture to ensure that only one NO2 group is substituted into the benzene ring (i.e. mononitration). If the temperature and nitronium ion (NO2+) concentration are too high (from quick addition of HNO3/H2SO4), then the chances of more than one NO2 group substituting into the benzene ring increases. This would give rise to unwanted dinitration products.

There are two reasons. 1. Presence of natural immunity 2. Immunity to superinfection Bacteria have defense mechanisms to combat phage infection. This comprises of restriction endonuclease system, the enzyme system which modifies the host DNA and specifically recognize and cleave the exogenous DNA. When a phage infects, only its genome is injected into the host cell. The injected DNA is recognized by the host restriction endonuclease system and is cleaved into fragments. The other reason is that immunity to superinfection. If a lysogenic phage infects a host cell, it integrates into genome into the host chromosome. At the same time, it also prevents the host from being infected by another lysogenic phage. The accumulation of cI protein in the host due to the existing prophage prevents infection by other phages. Some other reasons for resistance are lack of a receptor that facilitates the entry of the phage, lack of supporting machinery for the phage replication. Solution There are two reasons. 1.

The difference between maximization of value of the corporation and profit maximization and return to the shareholder and maximise their wealth is the difference of objectives of living one and non-living legal entity. The firms objective is not only the maximisation of the wealth or return to the Shareholders but creating values in the product is produced, development of the society in which it operates and growth of the persons attached to it like employees, suppliers and customers. On the other hand, it is the Shareholders whose objective to invest in the corporation is mainly to earn return on their investment. The shareholders wants the corporation to earns more and more profits for them every quater. The value of the corporation can be raised by only when the general society would recognises the company and its products and services.

Spore forming bacteria (prokaryotes) such as Bacillus anthracis can be dormant & survive even for 1000 years under the exposure of ultra-violet rays (the longest UV exposure). This is because of the following properties Bacillus subtilis produce dormant spores by sporulation ate suitable conditions and these spores are called as endospores. These endopores have the capability to survive at extreme temperatures followed by insufficient nutrient availability and their spore DNA is completely resistant to mutagens such as UV light, chemicals. They are also resistant to desiccation and resistant to extreme freezing and chemical disinfectants. Factor-1: These endospores possess very complex diversified structure that can withstand all the possible mutation inducing changes. These possess structural adaptations such as exosporium, hard spore coat and these are acts as very hard complex resistant materials, which can eliminate digesting enzymes such as lysozymes. These endospores possess cortex composed of peptidoglycan and it has a core wall that is present under the cortex and surrounds protoplast. These layers potentially protect spore DNA material. Factor-2: Core material of the spore also possesses calcium dipicolinate that enable stability of chromosomal DNA by protecting it from oxidizing agents. Inside the core material, spore possess DNA and it is covered by specifically small acid-soluble spore proteins an these are similar to chromatin-like proteins and enable in protecting DNA from heat as well as UV radiation inducing mutation. Factor-3: In order to keep the spore dormancy all the spore structural components formed and maintain signal transduction pathways, which further result in elevated activity of the cAMP- dependent protein kinase, triggers rapid encapsulation.

One case of paternity testing has been given in the figure. Four autoradiographs (autorads) that show DNA \"fingerprints\" for three individuals: a mother, her child, and the child\'s alleged father(said father/without proof). Each autorad compares the traits inherited by these three individuals - four traits are looked at, one for each autorad. Presence or absence of different alleles (called DNA fingerprints) has been compared in each case. These alleles (DNA fragments) differ in length from person to person; for this reason they are used as genetic markers. In case I-these alleles are A, B, C and D In case II-E, G and F In case III-H, I, J and K In case IV-L, M, N and O Ans 1 Case Genotype of Mother Genotype of Child Genotype of alleged father I A/D A/C B/C II G/G E/G E/F III I/J I/K H/K IV M/N M/O L/O Ans 2 In each case, child has inherited one copy of allele from mother and one from father so by looking at the genotype of child, contribution from the parents can be predicted (by comparing the genotype of all three persons) Case Genotype of child Allele inherited from mother Allele inherited from father I A/C A C II E/G G E III I/K I K IV M/O M O Ans-3 In each case, we can see that child has inherited one copy of allele from mother and one from father. So by making the comparison, it can be predicted that that the alleged father could be the biological father of this child. Ans 4 The DNA fingerprint assay is also useful in chimerism analysis after liver transplantation. Four percent of donor lymphocytes (transient lymphocytes) are present for up to 3 weeks after transplantation. If the donor lymphocytes persist, they can cause graft-versus-host disease (GVHD), which is an underdiagnosed and often fatal complication that occurs in approximately 1% of cases, usually 2 to 6 weeks after transplantation. The following cases illustrate the utility of the this assay in chimerism analysis. A liver transplant recipient presented with a skin rash 2 weeks after transplant, and a punch biopsy of the skin was obtained. The pathologist noted the presence of a lymphocyte infiltrate in the dermis. Possible causes included a drug reaction, a viral infection, or early GVHD. DNA was extracted from the area of lymphocyte infiltration, and DNA fingerprinting analysis was performed. The results showed that some of the lymphocytes were of donor origin, confirming the diagnosis of early GVHD. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1200713/ Case Genotype of Mother Genotype of Child Genotype of alleged father I A/D A/C B/C II G/G E/G E/F III I/J I/K H/K IV M/N M/O L/O Solution One case of paternity testing has been given in the figure.
