Chapters 16 & 17 Review Game

How is replication different in prokaryotes and eukaryotes?

• Replication in prokaryotes occurs in the cytoplasm, while in eukaryotes it occurs in the nucleus.

• Prokaryotic replication is slower than eukaryotic replication.

• Eukaryotic replication involves a single origin of replication, while prokaryotic replication involves multiple origins.

• Prokaryotic replication is bidirectional, while eukaryotic replication is unidirectional.

Which of the following enzymes bond DNA nucleotides together?

• Helicase

• DNA polymerase III

• Ligase

• DNA polymerase I

• Primase

Why are the leading and lagging strand replicated differently?

• Because DNA polymerase can only synthesize DNA in the 5' to 3' direction

• Because the leading strand is synthesized continuously while the lagging strand is synthesized in fragments

• Because the lagging strand requires more enzymes for replication

• Because the leading strand is shorter than the lagging strand

What are the base pairing rules?

• A pairs with T, and C pairs with G

• A pairs with C, and T pairs with G

• A pairs with G, and C pairs with T

• A pairs with T, and G pairs with C

Chargaff’s rule states that in DNA, the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of which other base?

• Cytosine

• Uracil

• Adenine

• Thymine

How is DNA compacted in a cell’s nucleus?

• By wrapping around histone proteins

• By forming a double helix structure

• By being dissolved in the nucleoplasm

• By attaching to the nuclear membrane

What is the difference between the replication of the leading and lagging strand?

• Leading strand is synthesized continuously, while lagging strand is synthesized in fragments.

• Leading strand is synthesized in fragments, while lagging strand is synthesized continuously.

• Both strands are synthesized continuously.

• Both strands are synthesized in fragments.

Why do we make the new DNA strand in the 5 prime to 3 prime direction?

• Because DNA polymerase can only add nucleotides to the 3' end

• Because DNA polymerase can only add nucleotides to the 5' end

• Because it is more energy-efficient

• Because it prevents mutations

Why do we describe DNA as antiparallel?

• Because the two strands run in the same direction.

• Because the two strands run in opposite directions.

• Because the two strands are identical.

• Because the two strands are parallel.

What must happen in order for transcription to begin in eukaryotes?

• RNA polymerase must bind to the promoter region.

• The DNA must be fully unwound.

• Ribosomes must attach to the mRNA.

• The mRNA must be transported to the cytoplasm.
