Single stranded RNA with segmented genes is found in ?
**Core Concept**
The question is testing the student's knowledge of viral classification based on their genetic material and genome structure. Specifically, it is asking about a type of virus characterized by a single-stranded RNA genome with segmented genes.
**Why the Correct Answer is Right**
The correct answer is a type of virus that has a segmented single-stranded RNA genome. This type of genome organization allows for a higher degree of genetic diversity and recombination, which can lead to increased virulence and antigenic shift. The segmented RNA genome is typically found in viruses belonging to the Orthomyxoviridae family, which includes influenza viruses. The segmented genes allow for the exchange of genetic material between different viral strains, making it easier for the virus to adapt and evolve.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because viruses with a single-stranded DNA genome are more commonly found in the family Herpesviridae, which includes herpes simplex virus.
* **Option B:** This option is incorrect because viruses with a double-stranded DNA genome are more commonly found in the family Adenoviridae, which includes adenovirus.
* **Option C:** This option is incorrect because viruses with a single-stranded RNA genome but non-segmented genes are more commonly found in the family Togaviridae, which includes rubella virus.
**Clinical Pearl / High-Yield Fact**
The segmented RNA genome of the Orthomyxoviridae family is responsible for the antigenic shift that occurs in influenza viruses, making them a significant public health concern.
**Correct Answer:** C. Influenza virus
