MCB 100 FULL Exam 1 (UIUC) Questions and Answers Graded A+ Question: What is the primary difference between prokaryotic and eukaryotic cells? Answer: Prokaryotic cells lack a true nucleus and membrane-bound organelles, while eukaryotic cells have a defined nucleus and organelles surrounded by membranes. Question: What is the role of ribosomes in bacterial cells? Answer: Ribosomes are responsible for protein synthesis, translating mRNA into polypeptide chains that fold into functional pr...

Case A 2-year-old girl presents with a fever and an inflamed throat. Her mother states the child does not want to eat. You decide to treat her with 7 days of penicillin. After 4 days, the mother calls your office to report that the child has not significantly improved. You suspect the child's infection may be caused by penicillin-resistant bacteria. Question What is the likely mechanism of resistance in this case? - CORRECT ANSWER Correct answer: Acquisition of the enzyme β-lact...
