Sample questions

1. Which of the following statements regarding the structural directionality of DNA is correct?

a.The two strands of the DNA double helix are anti-parallel

b.Purines pair with other purines to maintain helix stability

c.DNA strands are synthesized in the 3' to 5' direction

d.DNA polymerase adds nucleotides to the 5' end of a growing strand

2. Which enzyme is primarily responsible for relieving the torsional strain caused by DNA unwinding during replication?

a.DNA gyrase

b.DNA ligase

c.DNA primase

d.DNA helicase

3. What is the primary function of the DNA clamp during the replication process?

a.To join Okazaki fragments on the lagging strand

b.To synthesize the initial RNA primer for replication

c.To prevent DNA polymerase III from dissociating from the template

d.To unwind the double helix at the replication fork

4. Which of the following is a characteristic feature of the genetic code?

a.It is overlapping, allowing for multiple proteins from one sequence

b.It is punctuated by specific stop sequences between codons

c.It is degenerate, meaning one amino acid can be encoded by multiple codons

d.It is ambiguous, as one codon can specify different amino acids

5. According to the wobble hypothesis, which position of the codon on mRNA is bound less tightly to the anticodon?

a.The third position (3' end)

b.The first position (5' end)

c.The second position

d.The middle position
