E. Culture normal cells from affected individuals in the laboratory and treat them with a chemical that produces mutations specifically in a known tumor suppressor gene to see if the cells can be converted to tumor cells.

4. (Problem 5) What is the concept of dominance?

A. The concept of dominance states that when two different alleles are present in a genotype, both alleles can be observed equally in the phenotype.

B. The concept of dominance states that recessive alleles are only visible in the heterozygous condition.

C. The concept of dominance states that when two different alleles are present in a genotype, only the dominant allele is observed in the phenotype.

D. The concept of dominance states that an organism can only exhibit two alleles at a time.

E. None of these statements accurately explains the concept of dominance

(Problem 23) Some cancers are consistently associated with the deletion of a particular part of a chromosome. Does the deleted region contain an oncogene or a tumor-suppressor gene?

	A. Tumor-suppressor gene because their products normally inhibit inappropriate cell division
	B. Oncogene because their products normally induce appropriate cell division
	C. A deletion of either type would cause the same outcome.
	D. Oncogene because they usually are recessive mutations
	E. Oncogene because their products are often involved in signal-transduction pathways

23. Answer is C: Both gene deletion leads to cancer. Onco or proto oncogenes regulates cell cycle. Tumor supressor genes inhibit tumor formation. So deletion of thses both genes leads to Cancer

Problem 5: For the concept of dominance answer is C. if two different alleles present, the dominant alleles show s its phenotype

26. Answer is C. Radiation only target cancer cells but not normal cells. it is because the cancer cells rapidly divides than normal cells. due to this rapid division, the chromosomes are relatively more condensed state in cancer cells than normal cells. As condensed DNA is thic and easily targeted by radiation.

Problem 27. Answer is E
