(ii) Restriction enzymes are used in isolation and separation of DNA from other macromolecules. (iii) Downstream processing is one of the steps of rDNA technology. (iv) Disarmed pathogen vectors are also used in transfer of rDNA into the host.

Study the following statements regarding recombinant DNA technology and select the incorrect ones. (i) Taq polymerase extends the primers using the nucleotides provided in the reaction. (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. (v) To produce higher yields of a desired protein, host cells can be multiplied in a continuous culture. (vi) Downstream processing is one of the steps of polymerase chain reaction.

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.
