Question

Quizplus · Accepted Answer

The technique of introducing normal human genes into patient tissues using viruses is known as gene therapy. This method aims to correct genetic disorders that occur due to mutations or defects in a particular gene. The transfer of the normal gene replaces or supplements the defective gene, thus restoring the normal function of the gene product. Cloning involves the replication of identical copies of DNA or organisms. Antisense therapy involves using nucleic acid molecules that bind to a target gene's mRNA, blocking or altering its expression. DNA fingerprinting is a forensic technique that identifies unique DNA patterns in individuals.
