Which of the following statements about phagemid vectors is incorrect?
A) They contain components from both phage chromosomes and plasmids
B) They require a helper phage to replicate and package single stranded DNA particles in phage heads
C) An example of a phagemid vector is pUC118
D) Can allow researchers to perform directional cloning
E) All of these

Question

Quizplus · Accepted Answer

Phagemid vectors indeed combine elements from both phage chromosomes and plasmids (A), require a helper phage for replication and packaging (B), and allow for directional cloning (D). However, stating that pUC118 is an example of a phagemid vector (C) is incorrect, as pUC118 is a plasmid vector, not a phagemid. Therefore, the statement that all of these are correct (E) is the incorrect choice.
