(ii) Mention the types of Interferons. (iii) Why yeast cells are preferred than E.coil cells for producing recombinant interferons.

Why is E.coli not preferred for the production of recombinant interferons?

Who discovered Interferons? On which basis it was classified?

Saccharomyces cerevisiae is more suibtal for the production of recombinant interferons that E.coli.The reason is.

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.

Saccharomyces cerevisiae, acts as a best host than Escherichia coli for the production of recombinant interferons. Yes or No? Support your answer.

Assertion : Virus-infected cells secrete proteins known as interferons. Reason : Interferona protect the non-infected cells from bacterial infection.

Identify the correct statement(s). (i) Totipotency is the ability of single cell to produce a whole organism. (ii) Pluripotency refers to ability of stem cell with apotential to differentiate into any kind of germ layers. (iii) Unipotency refers to ability of stem cell to differentiate into one cell type. (iv) Oligopotency refers to stem cells to differentiate into few cell types.
