Question

Prokaryotic organisms have a single origin of replication, whereas eukaryotic organisms have many origins where replication occurs simultaneously. Which of the following is the most probable reason for this observation?

A) Prokaryotic DNA is single-stranded.B) Prokaryotic DNA is much smaller than eukaryotic DNA.C) Prokaryotes do not replicate their DNA.D) Prokaryotic DNA is replicated more slowly than eukaryotic DNA.

Answer 1

B) Prokaryotic DNA is much smaller than eukaryotic DNA

Step-by-step explanation:

As prokaryotic DNA is circular and much smaller than eukaryotic DNA, DNA repilcation is:

• Semi-conservative
• Semi-discontinous
• Bidirectional

The chromosome of the prokaryotes is a circular molecule of DNA. Replication begins at one origin of replication and proceeds in both directions around the chromosome.
