Question

when scientists know the specific identity of a gene causing a disease, it allows them to develop

gene splicing

gene mutations

gene analysis

gene therapy

Explanation:

Gene therapy aims to treat or prevent diseases by correcting genetic abnormalities. Knowing the disease - causing gene enables the design of gene - therapy strategies to introduce, remove, or modify genes. Gene splicing is a normal cellular process, gene mutations are changes in genes not a treatment developed from gene identification, and gene analysis is a prior step to knowing the gene identity rather than a development from it.

Answer:

gene therapy
