What is biotechnology?

Use of technology to control biological processes

Bt toxin is considered to be

organic insecticide produced by bacteria

Sequencing an individual person's genome

could lead to legal issues regarding discrimination

What is true about transgenic organisms?

Genome has 1+ genes inserted from another species

What is true about recombinant DNA

It's inserted into a sequence that does not exist in nature

How does Bt kill insects?

The toxic spore paralyzes the insect gut and kill it

3
Bt toxin is considered to be
organic insecticide produced by bacteria
a recombinant protein
A gene for modifying insect DNA
useful for humans to fight against insecticides
4
Sequencing an individual person's genome
could lead to legal issues regarding discrimination
all of the above
can help people who are already informed about medical treatments
is currently not possible
5
What is true about transgenic organisms?
Genomes are mated with a foreign DNA
Animals are inserted into a foreign environment
Genome has 1+ genes inserted from another species
None of the above
6
Plasmids are one type of cloning vector
True
False
7
What is true about recombinant DNA
It's removed from a sequence that does not exist in nature
It's inserted into a sequence that does not exist in nature
None of the above
It's inserted into a sequence that does already exists in nature
8
How does Bt kill insects?
The toxic spore paralyzes the insect gut and kill it
The spore rubs on the insect and paralyzes its legs
The spore contaminates the plant and blinds the insect
The bacteria injects a juice in the stomach of the insect
9
GMOs are created by introducing recombinant DNA into an organism by any means
True
False
10
What do restriction enzymes do?
Patch RNA with recombinant DNA
Cut DNA in specific places
Make transgenes using RNA fragment
Cut DNA in several sequences at once
11
What is true about PCR?
All are true
Its a technique for producing billions of copies of DNA
Used in cloning, forensics, and transgenics
PCR = polymerase chain reaction
12
What is true about cloning?
Dolly the sheep was a reproductive clone
All of the above
A clone is a genetically identical copy of a biological entity
Genes can be cloned, as can cells and plants
