You Isolate a Bacteriophage That Can Replicate in E

question 67

Multiple Choice

You isolate a bacteriophage that can replicate in E. coli. Through chemical analyses you determine that the only nucleic acid present is RNA. You isolate the RNA and put it in a test tube with all of the enzymes, amino acids, and RNAs necessary for translation. The RNA is translated directly, without being copied into a complementary strand first, and new infectious virions are made and released. What does this tell you about the bacteriophage?

• A) The viral genome is ssRNA of the plus sense.
• B) The viral genome is ssRNA of the minus sense.
• C) The bacteriophage is a retrovirus.
• D) The bacteriophage is probably a new strain and should be studied further.
