(iii)Name any two techniques that are useful in detecting cancers of internal organs.
(iv)Why are cancer patients after given a-interferon as part of the treatment? [Delhi 2014]
Answers
Answer:1) Proto-oncogenes are a group of genes that cause normal cells to become cancerous when they are mutated (Adamson, 1987; Weinstein & Joe, 2006). Mutations in proto-oncogenes are typically dominant in nature, and the mutated version of a proto-oncogene is called an oncogene.
2) computerized tomography (CT) scan, ultrasound and X-ray.
3) Interferons can help cells to defend themselves against viral infection and are used in the treatment of some cancers to boost the body's ability to eliminate cancer cells.
