Question

Tailed bacteriophage is

• A. Non-motile
• B. Actively motile in water
• C. Motile on bacterial surface
• D. Motile on surface of plant leaves

Answer 1

The correct option is A Non-motile

• Tailed bacteriophages are non-motile. They have a common origin and constitute family Caudovirales.
• Their structured tail is unique. Tailed phages share a series of high-level taxonomic properties and show many facultative features that are unique or rare in viruses e.g., lambda, Mu, and P1 phage.
  So option A is correct.
