Read the given statements and select the correct option. Statement 1: Both bacteria and yeast multiply very fast to form huge populations which express the desired gene. Statement 2: In recombinant DNA technology, human genes are often transferred into bacteria (prokaryotes) or yeast (eukaryotes).

Assertion: Mutation breeding is a process through which one gene from a parent transfer in to another and produce recombinant similar to parent. Reason : - Somatic hybridization does not induce variation.

An advantage of using yeasts rather than bacteria as recipient cells for the recombinant DNA of eukaryotes is that yeasts can

A bacterial cell was transformed with a recombinant DNA that was generated using a human gene. However, the transformed cells did not produce the desired protein. Reason could be (a) Human gene may have intron which bacteria cannot process (b) Amino acid codons for humans and bacteria are different (c) Human protein is formed but degraded by bacteria (d) all of the above

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.

Assertion :- In lac operon, a polycistronic structural gene is regulated by a common promoter & regulatory genes. Reason : Such arrangement is very common in bacteria & is referred as operon.

Assertion: DNA ligase plays an important role in recombinant DNA technology. Reason: The linking of antibiotic resistance gene with plasmid vector became possible by enzyme DNA ligase

Assertion :- In prokaryotes, control of the rate of transcriptional initiation is the predominant site for control of gene expression. Reason : The regulatory protein can act both positively (activators) & negatively (repressors)
