Which occurs in both the lytic cycle and the lysogenic cycle? a. destruction of host cell b. integration of viral and host genetic information c. production of virus particles d. hijacking of host cell's metabolic action i think a only occurs in the lytic cycle, although if you include it as the second part of the lysogenic cycle, it could be both. b is only in the lysogenic cycle. i put c, which was incorrect. i would consider d as part of the lytic cycle, but, if like a, you include it as the second part of the lysogenic cycle, it could be both. there is only one correct answer!

Answer is D. hijacking of host cell's metabolic action.

In lytic cycle, phages multiplies inside the host bacterium by using the protein synthesis machinery of the bacterium and new viral particles comes out by lysing or by rupturing the host bacterial cell wall. Examples are T phages, T2, T4, T6 etc.  

In lysogenic cycle, the phages does not undergo multiplication or induce breakdown of bacterium. In this the viral DNA gets integrated into the bacterial DNA without causing lysis and uses protein synthesis machinery of the bacterium to make viral protein. For example Lambda phages. Therefore, in both lytic and lysogenic cycle, virus uses host metabolism.  

this is a good question! i'll do some research and come back when i have the answer!

that is true   : ) hope this you
