Biotechnology (Video)
What controls inherited traits in an organism such as eye, hair or skin color?
genes
Clones are
genetically identical organisms
A transgenic organism is one that
has genes inserted into it from another organism
Biotechnology can be used in all of the following EXCEPT
human medicine
Mitosis is used
in plant tissue culturing, and to grow and develop tissues
Of the following, which is most likely to increase a plant's productivity?
increasing its rate of photosynthesis
In humans, genes control all of the following EXCEPT
nutrition
For natural sexual reproduction to take place, parents have to be
of similar species
Bioreactors are
organisms engineered to make specific compounds
Which animal's tissues are most similar to human's?
pig
The most commonly-used bacterium for gene transfer in plants is
Agrobacterium
The "BT" in BT corn stands for
Bacillus thuringiensis
All the information needed to make an entire organism is in a molecule called
DNA
Examples of biotechnology in animals include
animal cloning, cancer research, and human tissue replacement
In developing countries, "Golden Rice" may help prevent
blindness
The problem with many pesticides is that they may actually
cause an increase in some pests, kill beneficial insects, and be harmful to the environment
What are inserted into a cell's DNA to visually identify transgenic character?
marker genes
Simple cell division is called
mitosis
In nature, what are the two ways life reproduces and passes on genes?
mitosis and meiosis
This program discussed vaccinating people through
rice
According to this program, cats produce an allergen in their
saliva
Goals of biotechnology in plants include making plants
stronger, more productive, and more nourishing
When a gene is transferred into an organism, the organism is called
transgenic
Biotechnology may help some people in developing countries who need
vaccinations and disease prevention, better nutrition, and more food
Rice is usually very low in
vitamin A
