AP Biology - Unit 6 Exam
comprehensive Questions and Answers
with Verified Solutions
Question 1:
Purine
Answer:
Nitrogenous base with a double ring structure. Adenine and guanine
Question 2:
Pyrimidine
Answer:
Nitrogenous base with a single ring structure. Cytosine, thymine, and
uracil.
Question 3:
Prokaryotic vs Eukaryotic DNA
Answer:
Prokaryotes: DNA is found in nucleoid region and chromosomes are
circular Eukaryotes: DNA is found in nucleus and chromosomes are
linear
Question 4:
Plasmids
Answer:
Small, circular DNA molecules that are separate from the chromosomes.
Primarily found in prokaryotes and can be transmitted between bacteria.
, Question 5:
RNA vs DNA (3 each)
Answer:
RNA (3) 1. Ribose 2. SIngle Stranded 3. Uracil DNA (3) 1. Deoxyribose 2.
Double stranded 3. Thymine
Question 6:

Answer:
1. Conservative 2. Semi-Conservative 3. Dispersive Correct model:
Semi-conservative
Question 7:
Steps of DNA Replication
Answer:
1. Origins of replication 2. Unwinding 3. Primers 4. DNAP III 5. Okazaki
Fragments 6. DNAP I & DNA Ligase 7. Proofreading and Repair
Question 8:
1. Origins of Replication
Answer:
DNA replication begins at the origin of replication, which is at the 5' end.
Proteins attach to it and create a replication fork.
