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.
