Question

Which of the following is a common eukaryotic host for cloning?

• A. E.coli
• B. Yeast
• C. Xenopus
• D. Nurosopra

Hint:

E.coli = prokaryotic cloning host; Yeast = eukaryotic cloning host.

Answer 1

The Correct Option is B

Step 1: Recall host organisms used in cloning.
- Prokaryotic host: E.coli is widely used but it is prokaryotic.
- Eukaryotic host: Yeast, especially Saccharomyces cerevisiae, is a commonly used eukaryotic host.
Step 2: Checking the options.
- E.coli → Prokaryote, not correct here.
- Yeast → Eukaryote, widely used host for cloning. Correct.
- Xenopus → Used in developmental biology, not a cloning host.
- Nurosopra (likely meant Neurospora) → Model fungus, but not a primary host for cloning.
Step 3: Conclusion.
Hence, Yeast is the common eukaryotic host for cloning.
