Answer the questions 1 AND 2 about an experiment onmice If you were to fuse a tumor cell with a nontumor cellin culture, grow the daughter cells of the hybrid clone in culture,and then inject them into mice with defective immune systems,tumors would likely devolop in______of the mice a) nearly 100% b)75% c)50% d)25% e)less than 1% how do you know???? 2)What is the reason for the likely result of the experimentdescribed in the previous question a)tumorigenicity is dominant b)50% of the cells get a tumor suppressor gene c)tumor suppressor genes are recessive d)tumor suppressor genes are dominant e) the mouse immune system would be unable to destroy thehybrid cells 3)Nonhereditary retinoblastoma develops only when a)a somatic mutation inactivates the Rb gene b)a somatic mutation activates the Rb gene c)two somatic mutations inactivate two separate Rb genes d)one germ-line mutation and one somatic mutation inactivatethe Rb genes e) two germ-line mutations inactivate two separate Rbgenes 4) The tumor supppressor genes Smad2 and Smad4 encode a)growth factors receptors b)GTP -binding signal molecules c)transcription factors d)inhibitors that bind to transcription factors e)enzymes that inhibit cell proliferation 5)The tumor suppressor genes Smad2 and Smad4 encode a)growth factor receptors b)Gtp-binding signal molecules c)transcription factors d)inhibitors that bind to transcription factors e)enzymes that inhibit cell proliferation Answer the questions 1 AND 2 about an experiment onmice If you were to fuse a tumor cell with a nontumor cellin culture, grow the daughter cells of the hybrid clone in culture,and then inject them into mice with defective immune systems,tumors would likely devolop in______of the mice a) nearly 100% b)75% c)50% d)25% e)less than 1% how do you know???? 2)What is the reason for the likely result of the experimentdescribed in the previous question a)tumorigenicity is dominant b)50% of the cells get a tumor suppressor gene c)tumor suppressor genes are recessive d)tumor suppressor genes are dominant e) the mouse immune system would be unable to destroy thehybrid cells 3)Nonhereditary retinoblastoma develops only when a)a somatic mutation inactivates the Rb gene b)a somatic mutation activates the Rb gene c)two somatic mutations inactivate two separate Rb genes d)one germ-line mutation and one somatic mutation inactivatethe Rb genes e) two germ-line mutations inactivate two separate Rbgenes 4) The tumor supppressor genes Smad2 and Smad4 encode a)growth factors receptors b)GTP -binding signal molecules c)transcription factors d)inhibitors that bind to transcription factors e)enzymes that inhibit cell proliferation 5)The tumor suppressor genes Smad2 and Smad4 encode a)growth factor receptors b)Gtp-binding signal molecules c)transcription factors d)inhibitors that bind to transcription factors e)enzymes that inhibit cell proliferation
