BIOLOGY BIOL133-Exam 3- Chapters 12-15 Comment: Congratulations on the completion of Exam 3. Please let me know if you have any questions. Part 1 of 1 - 100.0 Points Question 1 of 40 2.5 Points If genes are completely linked, all the offspring will be _________.  A. hybrids  B. dominant  C. recombinants  D. parental  Exam 3- Chapters E. recessive Feedback: Correct Question 2 of 40 2.5 Points The codon AUG specifies the amino acid methionine. What would the tRNA anitcodon be that recognizes this codon?  A. UAC  B. GUA  C. AUG  D. GCA Feedback: Correct Question 3 of 40 2.5 Points Due to a random error by the aminoacyl tRNA synthetase, a tRNAVal was misloaded with Ile. What do you predict will result?  A. One protein will get Val inserted where Ile was supposed to go, leading to minor structural change in the protein.  B. One protein will get Ile inserted where Val was supposed to go, leading to major structural changes in the protein.  C. One protein will get Ile inserted where Val was supposed to go, leading to minor structural change in the protein.  D. The cell’s proteins will get Ile and Val inserted in the wrong places, leading to major structural changes in the proteins. Feedback: Learning Objective: Analyze how genes determine the proteins found in all cells Question 4 of 40 2.5 Points A mutation causes a codon to change from UAC to UAU, both of which specify tyrosine. This is an example of  A. a frameshift mutation  B. missense mutation  C. silent mutation  D. nonsense mutation Feedback: Learning Objective: Discuss the different types of mutations in DN
