Which of the following may possess an RNA genome?
A
Saccharomyces cerevisiae
B
Staphylococcus aureus
C
Influenza virus
D
Escherichia coli
Verified step by step guidance
1
Step 1: Understand the concept of RNA genomes. RNA genomes are found in certain viruses, not in cellular organisms like bacteria or fungi. Cellular organisms typically have DNA genomes.
Step 2: Analyze the options provided. Saccharomyces cerevisiae is a yeast (fungus), Staphylococcus aureus and Escherichia coli are bacteria, and Influenza virus is a virus.
Step 3: Recall that viruses can have either DNA or RNA genomes, depending on the type of virus. Influenza virus is an RNA virus, meaning its genetic material is RNA.
Step 4: Confirm that Saccharomyces cerevisiae, Staphylococcus aureus, and Escherichia coli are cellular organisms with DNA genomes, and therefore cannot possess an RNA genome.
Step 5: Conclude that the correct answer is Influenza virus, as it is the only option that may possess an RNA genome.
