Question

Transgenic mice may be used for testing of
A) The safety of vaccines
B) Efficiency of fertilizers
C) Doses of antibiotics
D) All of the above

Answer 1

Hint:Transgenic mice represent the mouse models featuring altered genomes retrieved for the purpose of studying the gene functioning.

Complete answer:
Transgenic animals feature modified genomes. In these animals, a foreign gene gets inserted within the animal genome for altering its DNA.
This transgenesis process is accomplished for the improvement of the genetic traits exhibited by the target animals.
Option A: These transgenic animals are used as representatives or model organisms for carrying out the evidence of the scientific basis.
This is a pre-clinical testing evaluation wherein the vaccines are purposely injected into the human bodies for the purpose of determining its safety and efficacy before putting it to the actual use in the human population.
Transgenic mice are developed on a large scale for the purpose of evaluating the vaccine safety and efficacy before it is being introduced into the market for the human trial qualification.
For example, the transgenic mice model organisms find a wide scale applicability for testing the vaccine efficacy against the polio infection. Therefore, this is the correct option.
Option B: Efficiency of fertilizers is always done by its direct application to the fields. Therefore, this is the incorrect option.
Option C: Transgenic mice are not used in the evaluation of the antibiotic doses. Therefore, this is the incorrect option.
Option D: As, only one option is correct, this is the incorrect option.

Thus, the correct option is (A)The safety of vaccines.

Note:Transgenic organisms are undeniable components of the scientific experimentation included under the fields of developmental biology and genetics.
