What is the basic difference between a tumor suppressor gene and a proto-oncogene?

Topic 1. Tumor-suppressor genes versus Proto-oncogenes. This is a library-research topic in which you are required to provide your sources. Mutations in tumor suppressor genes can contribute to or cause cancer, just as mutations in proto-oncogenes can also contribute to or cause cancer. However, tumor suppressor genes are very different from proto-oncogenes.

(a) What is the basic difference between a tumor suppressor gene and a proto-oncogene?

(b) Explain how mutations in these very different types of genes can cause or contribute to causing cancer.

Topic 2. Sexual Reproduction in Unicellular Eukaryotes. Watch the instructor’s video about “Sexual Reproduction in Unicellular Eukaryotes”, which is found in the Instructor Insights section for this week. For a single-celled species to be capable of sexual reproduction, the species must have both haploid and diploid forms

(a) Explain what diploid form of the organism must be capable of doing, for the species to reproduce sexually.

(b) Explain what haploid form of the organism must be capable of doing, for the species to reproduce sexually.
