(ii) Antibiotic resistance genes are considered as desirable genes in recombinant DNA technology. (iii) DNA fragments are separated according to their charge only, in agarose gel electrophoresis. (iv) Transformation is a procedure through which a piece of DNA is integrated in to the genome of a host bacterium.

Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer 1) if the data in statement I alone are sufficient to answer the question while the data in statement II alone are not sufficient to answer the question. 2) if the data in statement II alone are sufficient to answer the question while the data in statement I alone are not sufficient to answer the question. 3) if the data either in statement I alone or in statement II alone are sufficient to answer the question, 4) if the data even in both statements I and II together are not sufficient to answer the question. 5) if the data in both statements I and II together are necessary to answer the question. , A,B, C and D made their project presentation, one on each day, on four consecutive days but not necessarily in that order. On which day did ‘C’ make his presentation? I. The first presentation was made on 23rd, Tuesday and was followed by ‘D's presentation. II. 'A' did not make his presentation on 25th and one of them made his presentation, between A’s and B’s.

How many statements are correct? (a) Hind II always cut DNA molecules at particular point by recognizing a specific sequence of 6 bases. (b)After the restriction endonuclease action, single stranded portions which are overhanging stretches called sticky ends because they form nucleotide bonds with their complementary cut counter part. (c)The separated bands of DNA are cut out from the agarosegel and extracted from gel piece. This step is known as spooling. (d)Taq polymerase is used between annealing and extension of r-DNA technology.

Find out which among the following is true and which is false (i) Recombinant DNA technology has made it possible to engineer microbes, plants and animals such that they have novel capabilities. (ii) Genetically modified organisms have been created by using methods other than natural methods to transfer one or more genes from organism to another, generally using techniques such as recombinant DNA technology. (iii) GM plants have been useful in increasing crop yields, reduce post harvest losses and make crops more tolerant of stressess. (iv) Recombinant DNA technology process have made immense impact in the area of healthcare by enabling mass production of safe and more effective therapeutics. (v) since the recombinant therapeutics are identical to human proteins, they do not induced unwanted immunological responses.

Read the passage carefully and answer the question that follow. Certain words are printed in bold to help you locate them while answering some of the question: Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve realworld problems. It is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material, virtual technology, such as computer software and business methods, fall under this definition of technology. The word "technology" can also be used to refer to a collection of techniques. In this context, it is the current state of humanity's knowledge of how to combine resources to produce desired products, to solve problems, fulfill needs, or satisfies wants, it includes technical methods, skills, processes, techniques, tools and raw materials. When combined with another term, such as "medical technology" or "space technology," it refers to the state of the respective field's knowledge and tools. "State-of-the-art technology" refers to the high technology available to humanity in any field. Technology can be viewed as an activity that forms or changes culture. Additionally, technology is the application of math, science, and the arts for the benefit of life as it is known. A modern example is the rise of communication technology, which has lessened barriers to human interaction and, as a result, has helped spawn new subcultures, the rise of cyber culture has, at its basis, the development of the Internet and the computer. Not all technology enhances culture in a creative way, technology can also help facilitate political oppression and war via tools such as guns. As a cultural activity, technology predates both science and engineering, each of which formalizes some aspects of technological endeavour. Which two fields have been stated as an example which when combined with technology state the respective field's knowledge and tools?
