Some examples from this set of practice questions
1.
Explain the gene gun method with regards to GMOs.
Answer: Metal pellets coated with the desirable DNA are fired into plant cells. Cells take up the DNA & are cloned using micropropagation.
2.
Explain how gene therapy uses a cell-based delivery for treatment.
Answer: Cells are removed from the body & exposed to the vector (containing the desirable DNA) in a lab. Cells are then returned to the body after taking up the vector\'s DNA to hopefully produce the necessary protein.
3.
What is a dominant allele?
Answer: The allele (trait) that is expressed in the phenotype of the offspring.
4.
Phenotype
Answer: The physical appearance of an organism.
5.
Genotype
Answer: The genetic make-up of an organism.
6.
How does direct delivery work in relation to gene therapy?
Answer: A vector is injected directly into the body tissue where is is taken up by the cells.
7.
What is biotechnology?
Answer: The use of organisms, their parts or processes, for the creation of useful substances for humans.
8.
What is an allele?
Answer: An alternative version of a gene found in the same locus on homologous chromosomes.
9.
Recombinant DNA
Answer: A form of DNA that doesn\'t naturally occur in the genome of an organism. Created by combining DNA sequences that don\'t normally occur together.
10.
What is genetic engineering?
Answer: Altering the genome of an organism through a biotechnological process.
