Question

Varicella-zoster virus is a double-stranded DNA virus that causes chickenpox. How does its genome structure provide an evolutionary advantage over a single stranded DNA virus? 

Step-by-Step Solution

Answer

Both infections are made of DNA, yet single-abandoned DNA infections miss the mark on capacity to make the twofold helix. Consequently, twofold abandoned DNA infections have a more steady genome because of the free base matching, expanding the life expectancy of the infection's genome.

Introduction

Varicella zoster infection (VZV) is a solely human infection that has a place with the α-herpesvirus family. Essential contamination prompts intense varicella or "chickenpox", as a rule from openness either through direct contact with a skin injury or through airborne spread from respiratory droplets. After starting disease, VZV lays out long lasting idleness in cranial nerve and dorsal root ganglia, and can reactivate a very long time to many years after the fact as herpes zoster (HZ) or "shingles".

Explanation

Varicella-zoster infection (VZV), an omnipresent neurotropic herpesvirus, taints essentially all people. Essential contamination normally causes chickenpox (varicella), after which the infection becomes dormant in ganglia along the whole neuraxis.

The two diseases are made of DNA, yet single-deserted DNA contaminations come up short on ability to make the twofold helix. Subsequently, twofold deserted DNA diseases have an all the more consistent genome due to the free base coordinating, extending the future of the contamination's genome.

Final Answer

Twofold abandoned DNA infections have a more steady genome because of the free base matching, expanding the life expectancy of the infection's genome.
