Gene therapy involves:

  1. a. the introduction of recombinant proteins into individuals
  2. b. cloning human genes into plants
  3. c. the introduction of a normal gene into an individual carrying a mutant copy
  4. d. DNA fingerprinting
  5. e. none of these

Summary Introduction

Introduction: Gene therapy is a recombinant DNA based method that involves transfer of cloned genes into somatic cells to treat a genetic disorder. It is considered as a treatment option for disorders that are caused by mutation in single genes.

Explanation of Solution

Reason for correct answer:

Gene therapy is a procedure in which normal genes are transplanted into humans carrying the defective copies of genes, as a means of treating the genetic disease.

Option c. is given as “the introduction of a normal gene into an individual carrying a mutant copy”

Gene therapy involves the use of genes to treat or prevent the occurrence of the genetic disorder. It is done by introducing the normal functional genes to compensate for the abnormal genes, so that normal functional protein can be made. Hence, the correct answer is option c.

Reasons for incorrect answer:

Option a. is given as, “the introduction of recombinant proteins into individuals.”

Gene therapy involves recombination to get rid of the mutant copy of the gene by inserting a cloned normal gene. Hence, option a. is incorrect...
