Q. Consider the following:
1. Bacteria
2. Fungi
3. Virus
Which of the above can be cultured in artificial/synthetic medium?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: A

Why this Question) Commercial use of Bacteria and Fungi, also viruses in news. 

Ans) a 

Exp) Option a is correct.  

Statement 1 is correct. Bacteria can be grown in synthetic culture media. Researchers a had rewritten the DNA of the bacteria Escherichia coli, fashioning a synthetic genome four times larger and far more complex than any previously created.  

Statement 2 is correct. Fungi can be grown in synthetic culture media. Four allergologically important fungi, viz. Aspergillus fumigatus, Alternaria Penicillium notatum, and Cladosporium herbarum, were cultured in a pure synthetic medium.  

Statement 3 is incorrect. Viruses lack metabolic machinery of their own and are totally dependent on their host cell for replication, they cannot be grown in synthetic culture media.
