DQuestion 10 1 pts Which of the following occurs in lytic cycle but NOT in lysogenic cycle of a bacteriophage? Attachment to the host cell O Destruction of the host cell O Entry of the virus 0 Synthesis of viral proteins O Entry of the virus in the host cell

Explanation / Answer

1. The interactions between viral and host cell surface molecule is responsible for the specificity of virus. A virus is a small infectious agent that replicate only inside the living cells of other organisms.viruses can infect all types of life forms,from plants to animals to microorganisms including bacteria and archaea.Many viruses infect specific host cells i.e host specific.host specificity is due to specific attachement sites on the host cells called rec

2.attachement to the host cell occur in lytic cycle not in the lysogenic cycle of bacteriophage.
