Which of the Following Statements About Phagemid Vectors is Incorrect

Question

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

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.
