Several research studies are under way that involve the use of genetherapies to inhibit the growth of cancer cells. Oncogenes are mutant genes that are overexpressed and cause cancer. New gene therapies are aimed at silencing oncogenes by producing antisense RNA that recognizes the mRNAtranscribed from oncogenes. Based on your understanding of antisense RNA , explain how this strategy would prevent the growth of cancer cells.
