CHOOSE THE BEST ANSWER Which of the following correctly displays the Central Dogma of Biology?

TRUE OR FALSE Gaucher Disease is an autosomal recessive disease. A woman has a child with Gaucher Disease, but she is unsure who the father is. One possible father has Gaucher Disease and the other does not. Based on this information, can the woman be 100% certain who the father is?

CHOOSE THE BEST ANSWER The genetic code is said to be redundant but unambiguous. Which of the following best supports this statement?

CHOOSE THE BEST ANSWER The HER2 gene is a proto-oncogene that regulates the cell cycle. Mutations in HER2 are associated with the development of breast cancer.  As a proto-oncogene, how do you expect mutations in HER2 to disrupt the cell cycle?

CHOOSE THE BEST ANSWER Great jerboas and Severtzov’s jerboas are both small rodents native to arid regions, and they look nearly identical to each other. You sequence one gene present in both species, as well as the same gene in the Four-toed jerboa and the Lesser fat-tailed jerboa. You obtain the following results: Great jerboa:   GGATCCAGATCTGTCGAACTFour-toed jerboa:     GGATCGAGATCTGTGCAACTLesser fat-tailed jerboa: GGATCCAGATCGTTGGAAGTSevertzov’s jerboa: GGATCCAGATCTGTCGAGCT Based on the data, which species is most closely related to the Great jerboa?

CHOOSE THE BEST ANSWER Use the table below to transcribe and translate the following DNA sequence and identify the final polypeptide strand. DNA: 3′ – TTGGGACCACGGAACCGT – 5′

CHOOSE THE BEST ANSWER Foxes The Arctic fox (Vulpes lagopus) and the fennec fox (Vulpes zerda) both belong to the same genus but inhabit vastly different environments—one in the Arctic and the other in the Sahara desert. On the other hand, the Corsac fox (Vulpes corsac) and the Cape fox (Vulpes chama) live in semi-arid habitats in Central Asia and South Africa, respectively. You sequence one gene present in all four species and obtain the following results: Arctic fox: TCGGATCAGGACTACCTAGACape fox: TTGGGTGAGGATTGCGTATACorsac fox: TCGGATCAGGACTACTTAAAFennec fox: TTGGGTGAGGATCGCATATT Based on the data, which species is most closely related to the Arctic fox?

CHOOSE THE BEST ANSWER FOR EACH OPTION When one DNA molecule is replicated, the resulting two DNA molecules contain . This outcome results from the fact that the process of DNA replication is .

CHOOSE THE BEST ANSWER Alleles are alternate versions of _____ gene(s) that have ____ nucleotide sequences.

Digital Exams and Scholastic Dishonesty Copying, photographing, and distributing exam materials, as well as using digital learning tools (e.g., AI tools), violates the University’s policy of Scholastic Dishonesty. Consequences include failing the exam, failing the course, and administrative probation. To discourage such behavior, each student will receive a unique exam in terms of its wording and composition. This is a fair warning that if you distribute material from the exam, there is a high probability that it can be traced back to you. Exams will otherwise be equivalent in terms of length, content, and difficulty.
