Gene Therapy

Gene Therapy involves altering genes in the body's cells to treat disease through the production of good protein transcripts or the use of siRNA.

Transfection is the introduction of nucleic acids into animal cells, while transduction refers to virus-mediated DNA transfer.

Studying protein expression in eukaryotic cells allows for proper folding and post-translational modifications.
