Question

Identify the vector that infects E. coli cells containing F-plasmid and that has a single-stranded circular genome:}

• A. Agrobacterium tumefaciens
• B. YEp
• C. pBR322
• D. M13

Hint:

Always remember important features of different vectors such as their origin, their target species and the genome that they use.

Answer 1

The Correct Option is D

M13: M13 is a bacteriophage (a virus that infects bacteria) known for infecting E. coli cells containing an F-plasmid, and it has a single-stranded circular genome. This single stranded nature is very useful in many biological and biotechnological procedures. Agrobacterium tumefaciens: Agrobacterium tumefaciens is a bacterium used to transfer genes in plant cells. YEp: YEp is a yeast episomal plasmid and not related to E. coli. pBR322: pBR322 is a commonly used plasmid vector and not a virus, that is used in bacteria.
