Question

Inserting normal genes into a human chromosome is defined as:

a. DNA therapy.
b. gene therapy.
c. chemoinformatics.
d. chemical engineering.

Answer 1

Gene therapy involves replacing a faulty gene in a patient's cells with a functional gene to treat genetic disorders, often using a viral vector for delivery.

Step-by-step explanation:

Inserting normal genes into a human chromosome is defined as gene therapy. Gene therapy is a form of treatment for diseases that result from genetic mutations and involves the introduction of nonmutated, functional genes into the patient's genome. Often accomplished by using a viral vector like an adenovirus, the defective gene in the patient's cells is replaced with a working gene. This approach has been used experimentally to treat a variety of diseases, including severe combined immunodeficiency (SCID). Advanced forms of gene therapy even aim to correct the mutation at the original site in the genome.
