Question

drag each tile to the correct location.

sort the statements based on whether they describe dna replication in eukaryotes or prokaryotes.

prokaryotes | eukaryotes

tiles:

• replication takes place in the nucleus.
• there is only one origin of replication.
• there are multiple origins of replication.
• replication happens at just one point on the chromosome.
• replication takes place in the cytoplasm.
• replication occurs at multiple points along the chromosome.

Explanation:

Analyze cellular location of replication

• Prokaryotes lack a nucleus, so replication occurs in the cytoplasm.
• Eukaryotes contain a membrane-bound nucleus where genomic DNA replication takes place.

Analyze replication origins and points on the chromosome

• Prokaryotes typically have a single circular chromosome with a single origin of replication, meaning replication happens at just one point.
• Eukaryotes have large, linear chromosomes with multiple origins of replication, meaning replication occurs at multiple points along the chromosome.

Categorize the statements

• Prokaryotes:
• "There is only one origin of replication."
• "Replication happens at just one point on the chromosome."
• "Replication takes place in the cytoplasm."
• Eukaryotes:
• "There are multiple origins of replication."
• "Replication occurs at multiple points along the chromosome."
• "Replication takes place in the nucleus."

Answer:

Prokaryotes	Eukaryotes
Replication happens at just one point on the chromosome.	Replication occurs at multiple points along the chromosome.
Replication takes place in the cytoplasm.	Replication takes place in the nucleus.
