Which method allows for the correction of genetic diseases by replacing faulty genes?

Gene therapy is the method specifically designed to correct genetic diseases through the replacement or repair of faulty genes. It involves the introduction, removal, or alteration of genetic material within a patient's cells to treat or prevent disease. The primary goal of gene therapy is to address the underlying cause of a genetic disorder rather than simply managing symptoms.

This technique can utilize various approaches, including inserting a healthy copy of a gene into the genome of a patient or using other strategies to modify the expression of genes. This innovative method holds the potential to treat a wide range of genetic conditions and is at the forefront of modern medical research and treatment.

Transcription relates to the process of copying genetic information from DNA to RNA, which is a fundamental step in gene expression but does not involve repairing or replacing faulty genes. Genetic sequencing is the process of determining the sequence of nucleotides in DNA and provides valuable information for understanding genetic disorders but does not directly correct them. Cloning refers to creating a genetically identical copy of an organism or cell and is unrelated to treating genetic diseases on a genetic level.
