Read the following passage carefully and answer the given questions.
Bioactive molecule, cyclosporin A, that is used as an immunosuppressive agent in organ-transplant patients, is produced by the fungus Trichoderma polysporum. Statins produced by the yeast Monascus purpureus have been commercialised as blood-cholesterol lowering agents. It acts by competitively inhibiting the enzyme responsible for synthesis of cholesterol. Baculoviruses are pathogens that attack insects and other arthropods. The majority of baculoviruses used as biological control agents are in the genus Nucleopolyhedrovirus. These viruses are excellent candidates for species-specific, narrow spectrum insecticidal applications. They have been shown to have no negative impacts on plants, mammals, birds, fish or even on non-target insects. BOD refers to the amount of the oxygen that would be consumed if all the organic matter in one liter of water were oxidised by bacteria. The sewage water is treated till the BOD is reduced. Cheese, is one of the oldest food items in which microbes were used. Different varieties of cheese are known by their characteristic texture, flavour and taste. For example, the large holes in 'Swiss cheese' are due to production of a large amount of CO₂ by a bacterium named Propionibacterium sharmanii.
Propionibacterium sharmanii is used for the production of -

Amniocentesis should not be used for:

Identify the statements which are true for both RNA and DNA.
(A) Two nucleotides are linked through 3'-5' phosphodiester linkage.
(B) Nitrogenous bases are linked to the sugar moiety.
(C) Additional -OH is present at 2'-position in the sugar.
(D) 5-methyl uracil is present.

Medical termination of pregnancy (MTP) is considered relatively safe -

Which of the following is the primary female sex organ?

Read the following paragraph carefully and answer the given questions.
Certain types of leukocytes (WBC) of our body like polymorpho-nuclear leukocytes (PMNL-neutrophils) and monocytes and natural killer (type of lymphocytes) in the blood as well as macrophages in tissues can phagocytose and destroy microbes. For determining the cause of allergy, the patient is exposed to or injected with very small doses of possible allergens, and the reactions studied. The use of drugs like anti-histamine, adrenalin and steroids quickly reduce the symptoms of allergy. Heroin, commonly called smack is chemically diacetylmorphine which is a white, odourless, bitter crystalline compound. This is obtained by acetylation of morphine. Techniques like radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging) are very useful to detect cancers of the internal organs. Different species of Plasmodium (P. vivax, P. malaria and P. falciparum) are responsible for different types of malaria. Of these, malignant malaria caused by Plasmodium falciparum is the most serious one and can even be fatal.
Heroin, commonly called smack is chemically ______ which is a white, odourless, bitter crystalline compound.

The degradation of humus by microbes to release inorganic nutrients is known as-

_________ is the rate of a reaction at a particular moment of time.

A needle of length 4.5 cm is placed vertically 12 cm away from a convex mirror of focal length 15 cm. The magnification of the image produced is

BOD values of three water samples A, B and C were recorded as 20 mg/L, 10 mg/L and 50 mg/L. Which of the sample is/are the most polluted?

Recombinant DNA is directly injected into the nucleus of an animal cell. This method is known as-

A coil having 'n' turns and resistance \( 'R' \, \Omega \) is connected with a galvanometer of resistance \( '4R' \, \Omega \). What is the induced current in the circuit when this combination (coil+galvanometer) is moved in time \( t \) from a magnetic flux \( \phi_1 \) to \( \phi_2 \) ?
