Which of the following is a technique used to transfer genetic material from one organism to another?

  1. Gene therapy

  2. Polymerase chain reaction (PCR)

  3. DNA fingerprinting

  4. Genetic engineering


Correct Option: D
Explanation:

Genetic engineering is a technique that allows scientists to transfer genetic material from one organism to another, resulting in the production of genetically modified organisms (GMOs).

What is the primary function of stem cells?

  1. To produce red blood cells

  2. To repair damaged tissues

  3. To fight infection

  4. To regulate blood sugar levels


Correct Option: B
Explanation:

Stem cells are unspecialized cells that have the ability to develop into any type of cell in the body. This makes them useful for repairing damaged tissues and treating diseases.

Which of the following is a type of cancer that originates in the cells of the blood-forming tissues?

  1. Lung cancer

  2. Breast cancer

  3. Leukemia

  4. Colon cancer


Correct Option: C
Explanation:

Leukemia is a type of cancer that originates in the cells of the blood-forming tissues, such as the bone marrow and lymph nodes.

What is the role of antibiotics in medicine?

  1. To kill bacteria

  2. To reduce inflammation

  3. To lower blood pressure

  4. To treat viral infections


Correct Option: A
Explanation:

Antibiotics are drugs that are used to kill bacteria. They work by interfering with the bacteria's ability to grow and reproduce.

Which of the following is a type of vaccine that uses a weakened or inactivated form of a pathogen?

  1. mRNA vaccine

  2. DNA vaccine

  3. Live attenuated vaccine

  4. Recombinant vaccine


Correct Option: C
Explanation:

Live attenuated vaccines use a weakened or inactivated form of a pathogen to stimulate an immune response without causing disease.

What is the purpose of DNA fingerprinting?

  1. To identify individuals

  2. To diagnose diseases

  3. To study gene expression

  4. To develop new drugs


Correct Option: A
Explanation:

DNA fingerprinting is a technique that is used to identify individuals by analyzing the unique patterns of DNA in their cells.

Which of the following is a type of cell therapy that uses genetically modified T cells to fight cancer?

  1. Stem cell therapy

  2. Gene therapy

  3. CAR T-cell therapy

  4. Immunotherapy


Correct Option: C
Explanation:

CAR T-cell therapy is a type of cell therapy that uses genetically modified T cells to fight cancer. The T cells are modified to express a chimeric antigen receptor (CAR) that recognizes and binds to a specific antigen on cancer cells.

What is the role of monoclonal antibodies in medicine?

  1. To treat cancer

  2. To prevent infection

  3. To reduce inflammation

  4. To lower blood pressure


Correct Option: A
Explanation:

Monoclonal antibodies are laboratory-produced antibodies that are designed to target and bind to specific molecules. They are used in medicine to treat a variety of diseases, including cancer.

Which of the following is a type of genetic testing that is used to identify individuals who are at risk of developing a genetic disorder?

  1. Prenatal testing

  2. Newborn screening

  3. Carrier testing

  4. Genetic counseling


Correct Option: C
Explanation:

Carrier testing is a type of genetic testing that is used to identify individuals who carry a gene mutation that increases their risk of developing a genetic disorder. This information can be used to help individuals make informed decisions about their reproductive choices.

What is the purpose of tissue engineering?

  1. To grow new organs and tissues

  2. To repair damaged tissues

  3. To study cell behavior

  4. To develop new drugs


Correct Option: A
Explanation:

Tissue engineering is a field of research that focuses on the development of new methods for growing new organs and tissues. This research has the potential to revolutionize the way we treat diseases and injuries.

Which of the following is a type of gene therapy that uses a virus to deliver genetic material to cells?

  1. CRISPR-Cas9 gene editing

  2. RNA interference (RNAi)

  3. Viral vector gene therapy

  4. Gene silencing


Correct Option: C
Explanation:

Viral vector gene therapy uses a virus to deliver genetic material to cells. The virus is modified so that it cannot cause disease, but it can still deliver the genetic material to the cells.

What is the role of stem cells in regenerative medicine?

  1. To repair damaged tissues

  2. To treat genetic disorders

  3. To prevent infection

  4. To lower blood pressure


Correct Option: A
Explanation:

Stem cells are used in regenerative medicine to repair damaged tissues. They can be used to grow new tissue or to replace damaged tissue.

Which of the following is a type of cancer that originates in the cells of the breast?

  1. Lung cancer

  2. Breast cancer

  3. Leukemia

  4. Colon cancer


Correct Option: B
Explanation:

Breast cancer is a type of cancer that originates in the cells of the breast.

What is the purpose of genetic counseling?

  1. To provide information about genetic disorders

  2. To help individuals make informed decisions about their reproductive choices

  3. To develop new genetic tests

  4. To treat genetic disorders


Correct Option: A
Explanation:

Genetic counseling provides information about genetic disorders and helps individuals make informed decisions about their reproductive choices.
