Which of the following describes the relation between genetic engineering and the health of environment

  1. Bioremediation

  2. Biomagnification

  3. Eutrophication

  4. Bioaccumulation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bioremediation is the use of living micro organisms to degrade the environmental contaminants into less toxic forms. It uses naturally occurring bacteria and fungi or plants to degrade or detoxify substances hazardous to human health and the environment.

Which of the following ethic should be employed when conducting genetic engineering?

  1. Environmental ethic

  2. Organizational ethic

  3. Animal ethic

  4. Both A and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ethics means a branch of philosophy that deals with human conduct and how right or wrong an action or the motives behind an action may be. 
Environmental ethics and animal ethics should be strictly followed before when genetic engineering is been conducted as any technology should not harm the environment as well as animal life.

Which of the following statements support animal testing?

  1. Animal testing should use for both medical purpose and cosmetics.

  2. Animal testing prevents the widespread disaster by the release of chemicals.

  3. Animal testing is an inhuman process.

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A common argument for animal testing is that it serves as a safety screen to prevent human exposure to toxic chemicals or dangerous drugs before they are released for general use.

Which of the following is the ethics for the research with animals?

  1. Surgical procedure under appropriate anesthesia

  2. Research with professional standard

  3. Any animal can be used

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Anesthesia enables a animals to tolerate surgical procedures that would otherwise inflict unbearable pain.
Bioscience community accepts that animals should be used for research only within an ethical framework.

Animal suffering during testing can be minimized by which of these principles of ethics of animal biotechnology?

  1. Reduction

  2. Refinement

  3. Replacement

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Refinement refers to methods that minimise the pain, suffering, distress or lasting harm that may be experienced by research animals, and which improve their welfare. 

Refinement applies to all aspects of animal use, from their housing and husbandry to the scientific procedures performed on them.

The transgenic animals are those which have 

  1. Foreign DNA in some of its cells

  2. Foreign DNA in all its cells

  3. Foreign DNA and RNA in some of its cells

  4. Foreign DNA and RNA in all its cells
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Transgenic animals are animals that have had a foreign gene deliberately inserted into their genome. Such animals are most commonly created by the micro-injection of DNA into the pronuclei of a fertilised egg which is subsequently implanted into the oviduct of a  surrogate mother.
So, the correct answer is 'Foreign DNA in all its cells'

Mule is a product of

  1. Breeding

  2. Mutation

  3. Hybridisation

  4. Interspecific hybridisation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An interspecific hybrid is the product of mating between parents of two different species. A mule is the offspring of a male donkey and a female horse (mare). Mules are more patient, sure-footed, hardy and long-lived than horses, and they are considered less obstinate, faster, and more intelligent than donkeys.

So, the correct answer is 'Interspecific hybridisation'

Genetic engineering has been successfully used for producing

  1. transgenic mice for testing safety of polio vaccine before use in humans

  2. transgenic models for studying new treatments for certain cardiac disease

  3. transgenic Cow-Rosie which produces high fat milk for making ghee

  4. Animals like bulls for farm work as they have super power
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In research studies, animals that have been genetically engineered include cattle, pigs, chickens, goats, sheep, dogs, cats, fish, rats and mice. As scientists have sequenced the genomes of domestic animals, more is known about genes and the traits that they control.

So, the correct option is 'Transgenic mice for testing the safety of the polio vaccine before use in humans'.
