  1. Cow

  2. Sheep

  3. Goat

  4. Pig


Correct Option: D

Transgenic animals are generally produced for all of the following needs except

  1. Testing of chemical safety

  2. Testing of vaccine safety

  3. Stimulation of pathogenicity

  4. Production of pharmacologically important proteins


Correct Option: C

  1. To study vaccine safety

  2. In producing new varieties of mice

  3. In developing a show piece example

  4. In gene targeting


Correct Option: A

Which is correct regarding genetically engineered insulin using E. coli ________________.

  1. Difficult to purify

  2. Obtained in large unlimited quantities

  3. Possibility of transmission of animal diseases

  4. Insulin obtained varies in chemical structure


Correct Option: B

Which best describes a transgenic organism ?

  1. One that act as the donor for DNA to be moved into another organism

  2. One produced by cloning a mutant cell

  3. One that contains a foreign gene and is free- living in the environment

  4. Any genetically modified organism- resulting from laboratory research


Correct Option: C
Explanation:

Transgenic Organism or Genetically Modified Organisms (GMO) is an organism whose genetic material has been altered using genetic engineering techniques. Bacteria are the easiest organism to engineer and have been used for research, food production, industrial protein purification etc. There is a potential to use them for environmental purposes or as medicines.

So, the correct option is 'One that contains a foreign gene and is free-living in the environment'.

Genes found in plants and animals that are of actual or potential value to people are known as

  1. genetic resources

  2. biotic resources

  3. oceanic resources

  4. natural resources


Correct Option: A
Explanation:

There are various genes that are found in animals and pants that are of important use for the humans. These genes are extracted and then introduced into organisms by genetic engineering.

These genes are known as genetic resources.
So, the correct option is 'genetic resources'
