BIO 210 FINAL EXAM GENETICS 2024 ACTUAL EXAM 300 QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES ANSWERS ALREADY GRADED A+ A nucleotide is made up of what 3 components? - CORRECT ANSWERphosphate group, pentose sugar (deoxyribose in DNA and ribose in RNA), and a nitrogenous base What nitrogenous bases are purines - CORRECT ANSWER-Adenine and Guanine What nitrogenous bases are pyrimidines? - CORRECT ANSWERcytosine, thymine, uracil How can you differentiate between purines and pyrimidines? - CORRECT ANSWER-purines are double-ringed while pyrimidines are single-ringed What are the differences between DNA and RNA? - CORRECT ANSWERDNA: double stranded, has deoxyribose sugar(hydroxyl group at 2' carbon), bases: A, T, G, C RNA: single stranded, has ribose sugar(one oxygen is removed from the 2' Carbon), bases: A, U, G, C Nucleoside vs Nucleotide - CORRECT ANSWER-nucleoside: pentose sugar + nitrogenous base nucleotide: pentose sugar + nitrogenous base + phosphate group What type of bonds bind nucleotide chains? - CORRECT ANSWERPhosphodiester bonds A nucleotide is made up of what 3 components? - CORRECT ANSWERphosphate group, pentose sugar (deoxyribose in DNA and ribose in RNA), and a nitrogenous base What nitrogenous bases are purines - CORRECT ANSWER-Adenine and Guanine What nitrogenous bases are pyrimidines? - CORRECT ANSWERcytosine, thymine, uracil How can you differentiate between purines and pyrimidines? - CORRECT ANSWER-purines are double-ringed while pyrimidines are single-ringed What are the differences between DNA and RNA? - CORRECT ANSWERDNA: double stranded, has deoxyribose sugar(hydroxyl group at 2' carbon), bases: A, T, G, C RNA: single stranded, has ribose sugar(one oxygen is removed from the 2' Carbon), bases: A, U, G, C Nucleoside vs Nucleotide - CORRECT ANSWER-nucleoside: pentose sugar + nitrogenous base nucleotide: pentose sugar + nitrogenous base + phosphate group What type of bonds bind nucleotide chains? - CORRECT ANSWERPhosphodiester bonds
