You are studying cancer progression in mice. Your results show the following pathway in which two proteins play important roles in how mouse cell division is regulated. nutrients cell division Prot 1 Prot 2 You isolate a mutant strain of mice that have a Prot 1 mutation (Prot 1-). These mutant mice frequently develop cancer as young adults. You isolate a mutant strain of mice that have a Prot 2 mutation (Prot 2-). These mutant mice frequently develop cancer as young adults. Which of the following can you conclude from these observations? Select all that apply O Function of wild-type Prot 2 is to promote cell division when nutrients are present Function of wild-type Prot 2 is to promote cell division when nutrients are absent Function of wild-type Prot 1 is to inhibit cell'division when nutrients are absent Function of wild-type Prot 1 is to inhibit cell division when nutrients are present
