Question

some scientists are researching the possibility of using viruses to treat genetic disorders caused by a mutated gene. this treatment uses modified viruses to deliver dna containing the non - mutated gene to the affected persons cells. the type of treatment described above is called
plasmid transfer
gene therapy
genetic screening
genome sequencing

Explanation:

Gene therapy aims to treat genetic disorders by delivering non - mutated genes to cells using modified viruses. Plasmid transfer is about moving plasmids, genetic screening is for detecting genetic variations, and genome sequencing is determining the DNA sequence.

Answer:

B. gene therapy
