Which of the following best describes gene therapy?
treating diseases using traditional pharmaceutical drugs
performing surgery to correct genetic abnormalities
modifying cells at the genetic level to treat or prevent diseases
using stem cells to regenerate damaged tissues
|
Which of the following vectors CANNOT be used to deliver DNA into cells during gene therapy?
plasmids
mosquitoes
liposomes
viruses
|
How does gene therapy typically counteract recessive disorders?
by adding functional dominant alleles to silence non-functional recessive alleles
by adding a normal recessive allele
by removing the faulty recessive alleles from the DNA
by inserting DNA sequences that inactivate harmful dominant alleles
|
What is the purpose of silencing faulty dominant alleles in gene therapy?
to activate the recessive alleles
to prevent the dominant alleles from causing harm
to remove the dominant alleles from the DNA
to replace the dominant alleles with recessive alleles
|
Which type of gene therapy alters body cells?
neither somatic nor germline gene therapy
germline gene therapy
both somatic and germline gene therapy
somatic gene therapy
|
What is the main difference between somatic and germline gene therapy in terms of inheritance?
neither somatic nor germline gene therapy modifications are inherited
somatic gene therapy modifications are inherited, while germline modifications are not
both somatic and germline gene therapy modifications are inherited
germline gene therapy modifications are inherited, while somatic modifications are not
|
Which of the following is NOT an ethical benefit of gene therapy?
extending lives by treating diseases
enhancing quality of life
allowing carrier parents to have children free from genetic disorders
can be used for aesthetic improvements in children
|
What is a potential misuse of gene therapy?
treating serious genetic diseases
enhancing aesthetic attributes rather than addressing medical needs
reducing the overall disease burden in the population
allowing carrier parents to have children free from genetic disorders
|
Which of the following is a challenge associated with somatic gene therapy?

getting healthy alleles into the nucleus
maintaining the expression of healthy alleles
all of the above
