Question

The bacteriophage M13 vectors belong to a group of phages called as __________

(a) skinny or filamentous phage

(b) M phage group

(c) single stranded phage

(d) double stranded phage

I had been asked this question in homework.

My question is based upon BAC Vector, M13 and its Derivatives in division Other Vector Systems for E of Genetic Engineering

Answer 1

Right answer is (a) skinny or filamentous phage

To explain I would say: Bacteriophage M13 vectors belong to a group of vectors known as skinny or filamentous phage. They have a dimension of 850 nm * 6 nm * 6nm. They are very useful as they convert the double stranded DNA into single stranded DNA.
