The correct Answer is:
To solve the question regarding the cryptogram of T2 coliphage, we can break it down into several steps: ### Step-by-Step Solution: 1. **Understanding Cryptogram**: A cryptogram is a type of puzzle that consists of a short piece of encrypted text. In the context of viruses, it represents the essential characteristics of the virus in a coded format. 2. **Identify the Type of Nucleic Acid**: The T2 coliphage is known to have double-stranded DNA. This can be represented in the cryptogram as "D/2", where "D" stands for DNA and "2" indicates that it is double-stranded. 3. **Determine Molecular Weight**: The molecular weight of the nucleic acid in T2 coliphage is given as 130 million daltons. This can be represented in the cryptogram as "130". 4. **Calculate Percentage of Nucleic Acid**: The percentage of the nucleic acid in T2 coliphage is 30%. This can be represented as "30". 5. **Shape of the Virus**: The shape of T2 coliphage is not definitively known, so it can be represented as "X/X" in the cryptogram, where "X" indicates an unknown shape. 6. **Infection Mechanism**: T2 coliphage infects bacteria directly and does not require any vector for infection. This can be represented as "B/O", where "B" indicates bacteria and "O" indicates no vector is required. 7. **Combine All Components**: Now, we can combine all the components to form the complete cryptogram for T2 coliphage. It will be represented as: - D/2 (for double-stranded DNA) - 130 (for molecular weight) - 30 (for percentage of nucleic acid) - X/X (for unknown shape) - B/O (for infection mechanism) Therefore, the complete cryptogram is: **D/2 130/30 X/X B/O**. ### Final Answer: The cryptogram of T2 coliphage is: **D/2 130/30 X/X B/O**. ---
