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.

Study the given figure carefully and select the incorrect statements regarding this. (i) It represents a typical agarose gel electrophoresis in which lane 1 contains undigested DNA (ii) Smallest DNA bands are formed at A and largest DNA bands are formed at B (iii) The separated DNA fragments can be visualized after staining in the visible light (iv) The separated DNA bands are cut out from the agarose gel and extracted from the gel piece. this step is known as elution.

Read the following statements and select the correct option. (I) E.coli cloning vector pBR322 have several restriction sites , ori , antibiotic resistance genes and rop. (II) Competent bacterial cells cannot take up foreign DNA. (III) In elution ,the separated bands of DNA are cut out from agarose gel and extracted from the gel piece. (IV) The downstream processing and quality control testing vary from product to product .
