Q. A nutritionally wild type organism, which does not require any additional growth supplement is known as :
- Phenotype
- Holotype
- Auxotroph
- Prototroph
Solution :
Correct option : D A nutritionally wild-type organism, which does not require any additional growth supplement is known as prototroph. It has the ability to synthesize all of its amino acids, nucleic acids, vitamins, and other cellular constituents from inorganic nutrients. Auxotrophs, on the other hand, are mutant strains that lack one or more enzymes required for metabolizing nutrients and can only grow on supplemented media. Thus, the correct answer is option D.
