some cancer cells are missing a key protein needed to repair double-strand dna breaks. they survive by relying on alternative dna repair mechanisms. to treat these cancers, researchers have developed drugs that do which of the following?

Respuesta :

B) promote alternate DNA repair mechanisms in normal cells. Mutations in certain DNA repair mechanisms increase the vulnerability to different cancer forms.

While it is illogical to believe that stopping DNA repair processes could be a viable strategy for eliminating cancer cells, careful identification of DNA repair proteins that play essential roles in maintaining DNA integrity is a strategy that appears to have promise in the arsenal of cancer treatments.

Long recognized as a contributing element in the development of cancer, DNA damage. Erroneous DNA repair can result in mutations or chromosomal abnormalities that influence tumor suppressor and oncogene genes, causing aggressive development in cells. Cancer can be caused by genetic abnormalities. However, DNA damage continues to offer a crucial route for chemo- and radiation, in addition to being a primary factor in the genesis of cancer.
