LC Genetic Engineering Quiz

What does Genetic Engineering refer to?

• The natural evolution of organisms

• Laboratory techniques to alter the DNA of an organism

• The process of natural selection

• The breeding of animals

What is a GMO?

• Genetically Modified Organism

• Genetically Mutated Organism

• Genetically Managed Organism

• Genetically Measured Organism

Which of the following is an example of Genetic Engineering use?

• Natural pollination

• Golden Rice

• Traditional farming

• Organic composting

What is the purpose of using restriction enzymes in Genetic Engineering?

• To replicate DNA

• To cut DNA at specific sites

• To synthesize proteins

• To transport DNA

How does Genetic Engineering break the species barrier?

• By allowing natural breeding between species

• By transferring genes from one species to another

• By creating new species through evolution

• By cloning entire organisms

What is the primary role of a cloning vector in genetic engineering?

• To cut DNA at specific sequences

• To replicate independently and accept foreign DNA

• To stick DNA strands together

• To remove chromosomes from the source

Which enzyme acts as a "genetic glue-stick" in the process of genetic engineering?

• Cloning vector

• Restriction enzyme

• DNA ligase

• Plasmid

What is the function of a restriction enzyme in genetic engineering?

• To replicate DNA independently

• To cut DNA at specific base sequences

• To stick DNA strands together

• To express the desired gene

In the genetic engineering process, what is the purpose of the isolation step?

• To stick DNA strands together

• To cut DNA at specific sequences

• To remove the chromosome with the desired gene from the source

• To replicate DNA independently

What is the role of DNA Ligase in the process of ligation?

• It helps to replicate DNA strands.

• It helps to bond two pieces of DNA to form a single strand.

• It helps to break down DNA into smaller pieces.

• It helps to transcribe DNA into RNA.
