A lytic virus cycle leads only to cell lysis, and a lysogenic virus cycle involves phage genome integration into the host genome.

In lysogenic virus cycle,the virus DNA replicates itself using a host DNA while in lytic virus cycle,the virus replicates it's DNA and destroys the host cell.

Viruses undergo two(2) types of DNA replications which are lysogenic cycle or the lytic cycle.

In the lysogenic cycle, a bacteriophage virus makes it's way into a bacteria cytoplasm and deposits it's DNA.The DNA of the virus is further replicated by the bacterial proteins,this replication continues with the aid of the bacteria machinery until the virus DNA eventually switch to the the lytic cycle.

In lytic cycle,lots of the virus DNA are produced and encapsulated in capsids or proteins covers.

The capsids are further released into the environment to infect other bacteria and the cycle continues.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
