All of the following statements about genetic engineering are correct EXCEPT
A) recipient strains of bacteria to be utilized for cloning of foreign DNA should have mutated restriction enzyme systems.
B) recombinant plasmids are introduced into bacterial cells by transformation.
C) recombinant DNA clones containing eukaryotic DNA inserts can be made to synthesize eukaryotic proteins in bacterial cells.
D) bacterial plasmid vectors replicate and lyse bacterial cells forming plaques.
E) DNA ligase is utilized to covalently join DNA molecules in the construction of recombinant molecules.

Question

Quizplus · Accepted Answer

Bacterial plasmid vectors do not lyse bacterial cells to form plaques; this is a characteristic of bacteriophages, not plasmids. Plasmids replicate within bacterial cells without causing lysis.
