RNA containing viruses are called as

Options

A. (a) ribocubica
B. (b) ribobinala
C. (c) ribovira
D. (d) deoxyvira

Answer

To answer the question "RNA containing viruses are called as," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification of Viruses**:
- Viruses are classified into different categories based on their genetic material, which can either be RNA or DNA.

2. **Identify the Phylum**:
- According to the classification by Thornberry in 1968, viruses are divided into the phylum "Vira." This phylum is further divided into two subphylum: "Ribovira" (RNA viruses) and "Deoxyvira" (DNA viruses).

3. **Focus on RNA Viruses**:
- Since the question specifically asks about RNA-containing viruses, we will focus on the subphylum "Ribovira."

4. **Subclasses of Ribovira**:
- The subphylum "Ribovira" is further divided into subclasses, which include:
- Ribohelica (helical shape)
- Ribocubica (cubical shape)
- Ribobinala (long tail)

5. **Evaluate the Options**:
- The options given are:
- A. Ribocubica
- B. Ribobinala
- C. Ribovira
- D. Deoxyvira
- Ribocubica and Ribobinala are subclasses of RNA viruses, but they are not the general term for all RNA viruses. Deoxyvira refers to DNA viruses.

6. **Select the Correct Answer**:
- The term that encompasses all RNA-containing viruses is "Ribovira." Therefore, the correct answer is **C. Ribovira**.

### Final Answer:
RNA containing viruses are called as **Ribovira**.
