Which is incorrect about E coli

Options

A. It is diploid
B. It is found in human intestine
C. Transformation, Transduction, Conjugation can show
D. Can be used in Recombinant DNA technology

Answer

To determine which statement about E. coli is incorrect, let's analyze each option step by step:

1. **Option 1: It is deployed.**
- This statement is ambiguous. The term "deployed" is not typically used in the context of describing bacteria like E. coli. E. coli is a bacterium that exists naturally in the intestines of humans and other warm-blooded animals, and it is not something that is "deployed" in a conventional sense.

2. **Option 2: It is found in the human intestine.**
- This statement is correct. E. coli is a common bacterium that resides in the intestines of humans and other warm-blooded animals. It plays a role in digestion and is a normal part of the gut microbiota.

3. **Option 3: Transformation, Transduction, Conjugation.**
- This statement is correct. E. coli is known for its ability to undergo transformation (uptake of DNA from the environment), transduction (transfer of DNA via bacteriophages), and conjugation (transfer of DNA through direct contact between bacteria). These processes are important for genetic exchange and diversity.

4. **Option 4: It can be used in recombinant DNA technology.**
- This statement is correct. E. coli is widely used in recombinant DNA technology as a host organism for cloning and expressing genes due to its well-understood genetics and rapid growth.

Based on the analysis, the incorrect statement about E. coli is **Option 1: It is deployed.**
