QUESTION 7 What are the potential consequences of un-repaired DNA damage (i.e. mutations) (select all that apply)? A. Somatic mutations lead to changes in fitness for the affected individual ONLY B. Germ line mutations lead to cancer or other disease in the affected individual ONLY OC. Somatic mutations lead to cancer or other disease in the affected individual ONLY D. Germ line mutations lead to generation of new alleles that are passed on to the progeny E. Germ line mutations lead to changes in fitness for the progeny OF. Germ line mutations lead to changes in fitness for the affected individual ONLY G. Mutations are always detrimental OH. Somatic mutations lead to changes in fitness for the progeny Ol. Mutations are always beneficial J. The impact of a mutation is dependent on selective pressures OK. Somatic mutations lead to generation of new alleles that are passed on to the progeny QUESTION 8 What can we conclude from Beadle and Tatum's work on Arginine biosynthesis (select all that apply)? A. Mutations occur spontaneously B. Each gene (or transcript) controls the synthesis of a specific enzyme or protein C. Mutations that disrupt the function of the encoded protein will alter specific phenotypes D. Mutations that lie in the same gene will “complement" one another E. There are 4 genes involved in the synthesis of arginine OF. One gene is responsible for all four steps for arginine biosynthesis
