Question
Latent viruses, such as herpes virus, chickenpox, and HIV, exhibit a _____ viral life cycle. Herpes virus for instance will cause lesions on the skin during _____ infection, and then the virus may travel down ________ neurons to spinal ganglia. Once there, the viral ______ will remain in a latent state for perhaps years. During a subsequent ______ event, often related to stress, the virus becomes reactivated and migrates back down the original neuron through which it traveled causing new _________ to develop. Chickenpox virus follows a similar life cycle, exhibiting a latent period that can last for decades and where reactivation of the virus leads to the disease known as _________. HIV is somewhat different, however, in that the viral genome integrates into the host cell chromosome and survives as a ________ during its latent period. The provirus is replicated and passed on to numerous CD4+ cells during this time, when reactivated, these cells are killed and the patient in most cases develops __________ over time.Explanation / Answer
Latent virus such as herpes,CHICKEN pox and HIV EXIHIBIT A lysogenic viral cell cycle. (Latency is ability of virus to be dormant as in lysogenic cycle.)
Herpes virus for instance will cause lesson on the skin during primary Infection and then virus may travel down sensory neuron to spinal ganglia.
Once there the viral. Genome Will remain in latents stage for perhaps years.
During a subsequent infection event often related to stress the virus becomes reactivated and migrates back down the original neuron through which it traveled causing new lession to develop.
Chicken pox a similar cye exhibiting a latent period that can last for decades and where reactivation of the virus leads known as shingles. (This a medical condition due to reemergence of pox)
HIV is somehat different however in that viral genome integrates io the host cell chromosome and servive as a Provirus. (Stage when viral geno!e get integrated to host genome)
The provirus is replicated an passed on to numerous CD4 CELLS DURING this time when reactivated these cells are killed and the patients in most cases develops AIDS over time.
