Q & A

What are the supporting sciences in modern biotechnology?

The supporting sciences in modern biotechnology include microbiology, biochemistry, genetics, cell biology, chemical engineering, and enzymology.

What are the four basic principles of modern biotechnology?

The four basic principles of modern biotechnology are: 1) Use of biological agents, 2) Use of specific methods, 3) Production of derived products, and 4) Involvement of various scientific disciplines.

What are some advantages of modern biotechnology?

Some advantages include predictable results, targeted genetic manipulation, and the ability to create organisms with new traits that don't naturally occur.

What are the main disadvantages of modern biotechnology?

Disadvantages include high production costs, the risk of monoculture, genetic erosion, the need for advanced technology, and the uncertainty of long-term effects.

What is genetic engineering, and how does it work?

Genetic engineering is the manipulation of genes to produce new products by adding or removing specific genes to alter characteristics. It involves identifying, extracting, cloning, and transferring genes into new organisms.

What are transgenic plants and how are they created?

Transgenic plants are plants that have been genetically modified to contain new genes for desired traits. They are created by identifying the target gene, extracting it from another organism, cloning it using plasmids, and transferring it into the plant using methods like agrobacterium transformation or electroporation.

What are the desired traits in transgenic plants?

Desired traits in transgenic plants include resistance to pests, tolerance to herbicides, and improved shelf life of fruits.

What is the role of plasmids in the creation of transgenic plants?

Plasmids are small circular DNA molecules found in bacteria. They are used to clone the desired gene and facilitate its transfer into the plant.

What are transgenic animals, and what are their uses?

Transgenic animals are genetically modified animals created to exhibit specific traits, such as producing high-quality milk or meat, growing rapidly, or having enhanced nutritional content.

What are the key steps involved in creating transgenic plants?

The key steps include identifying the gene, extracting it from another organism, cloning it using plasmids, and transferring it into the plant using methods like agrobacterium transformation or electroporation.
