Assertion: For toxicity testing, transgenic animals are made to carry genes which make them more sensitive to toxic substances.
Reason: Transgenic animals are exposed to toxic substances to study their effects.
The correct answer is option 'B', which means both the assertion and reason are correct.
Explanation:
Toxicity testing is a crucial step in determining the safety of chemicals, drugs, and other substances. It involves studying the effects of these substances on living organisms, including animals. Transgenic animals, which are animals that have had their genetic material manipulated, are often used in toxicity testing.
1. Transgenic animals:
Transgenic animals are created by introducing specific genes into their genome. These genes can be from the same species or from a different species. The purpose of creating transgenic animals is to study the function of specific genes and their effects on the organism.
2. Making animals more sensitive to toxic substances:
In toxicity testing, the aim is to determine the toxicity levels and potential adverse effects of substances. To achieve this, transgenic animals are sometimes engineered to carry genes that make them more sensitive to toxic substances. These genes may enhance the expression of certain enzymes involved in metabolizing and detoxifying substances or make the animals more susceptible to the toxic effects of the substances.
3. Exposure to toxic substances:
Once the transgenic animals are created, they are exposed to various toxic substances under controlled conditions. The substances may include chemicals, drugs, pollutants, or other potentially harmful agents. The animals are monitored and observed for any adverse effects, such as changes in behavior, physiology, or organ function.
4. Studying the effects:
The reason for exposing transgenic animals to toxic substances is to study their effects. By observing the animals' responses, researchers can gain insights into the toxicity levels, mechanisms of action, and potential risks associated with the substances being tested. This information is crucial in assessing the safety and potential hazards of substances before they are introduced into the market or used in human or animal populations.
In conclusion, the assertion that transgenic animals are made to carry genes that make them more sensitive to toxic substances is correct. The reason that transgenic animals are exposed to toxic substances to study their effects is also correct. Both the assertion and reason are interrelated and necessary steps in toxicity testing.
