Read the information given in the passage and answer the questions that follow. DNA (Dioxyribo Nucleic Acid) is found in the nucleus of most of the cells. It controls functioning of the cell and also determines how an organism looks like and functions. A segment of DNA that determines a specific trait in an organism is called gene. Gene consists of four types of nucleotides that differ from each other in terms of bases. Four types of bases are Adenine, Thymine, Cytosine and Thymine. It is the unique sequence of these bases (in nucleotides) that codes of different information. Tools of genetic Engineering have made it possible to transfer these unique sequences from one organism to another. Genetic engineers use restriction enzymes to remove a gene from a donor organism’s DNA and insert it into a molecule of carrier DNA. This process is called recombination. Finally the recombinant DNA is introduced into egg of a multicellular organism at the time of fertilization. The genes containing nucleotide sequences from other organism are called transgenes. That is why the organisms are also called transgenics. This technology is being used in Plant Science, frequently. Transgenes present in a cell multiply with the organism and pass on to the next generation through pollens and egg cells. Genetic engineering manipulates gene structure at the level of the

Read the following passage and answer the questions that follow. When solids, liquids or gases are dissolved in a liquid they make a solution. The substance (solid, liquid or gas) being dissolved is called the solute and the liquid that does the dissolving is called the solvent. Solutions which use water as the solvent are called aqueous solutions. When you dissolve a spoon of instant coffee in hot water or add water to some cordial syrup, you are making an aqueous solution. The concentration of an aqueous solution refers to the amount of solute that has been dissolved in a fixed amount of water. For example, if a saline solution (made from salt dissolved in water) has a concentration of 10 g/L, then we know that 10 g salt has been dissolved in 1 litre of water solvent. The concentration of a solution can also be described by the proportion of the solute to solution either by mass or by volume The by mass concentration is used when a solid is dissolved in a solvent. This is calculated by dividing the mass of the solute (in grams) by the mass of the solution (also in grams) and the result converted into a percentage. It is important to note that the mass of the solution is equal to the mass of the solute plus the mass of the solvent. One millilitre of water has a mass of 1 gram. When solute is a liquid, the by volume concentration is used. In this case, the volume of the solute is divided by the volume of the solution and the result is again converted into a percentage. It does not matter which volume unites (millilitres, litres or cubic centimetres) are used, provided that the same unit is used for both the solute and the solution. The table below indicated how much sugar can be found dissolved in different beverages. Type of drink Amount of drink (common size) Sugar content per can/pack 1 teaspoon = 5 grams Soft drink 375 mL 8-9 tsp Apple drink (25% pure apple juice; 75% water) 250 mL 5 tsp 100% pure orange juice 250 mL 3 tsp 100% pure vegetable juice 250 mL 2-3 tsp water 600 mL 0 tsp Which of the following statement is true?
