Question

All tailed bacteriophagic cells contain

• A. dsDNA
• B. dsRNA
• C. ssDNa
• D. ssRNA

Answer 1

Answer: (A)

dsDNA

Tailed bacteriophages are the virus which infects the bacteria and archaea. They have double stranded DNA. The double stranded DNA is mainly covered by icosahedral capsid with a tail attached to one vertex. The tail attaches to the host and transfers the genetic material into the host. The T${}_4$ bacteriophages are the example of tailed bacteriophage.

So, the correct answer is option A.
