Which of the following statements about tumor suppressor genes is false? Gene amplification of a tumor suppressor gene is less dangerous than gene amplification of a proto-oncogene. Cells with one functional copy of a tumor suppressor gene will usually proliferate faster than normal cells. p53 is a tumor suppressor gene. Inactivation of tumor suppressor genes leads to enhanced cell survival and proliferation. A mutation in a tumor-suppressor gene that renders the tumor-suppressor protein to be constitutively active often leads to cancer.

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression. c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression. d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
