You have learned that having linear DNA has consequences, the major one being that the DNA gets shortened every time it replicates, something that does not happen with the circular DNA found in prokaryotes
What, then, is the advantage of having linear DNA?
A. Linear DNA is easier to package than
circular DNA.
B. Linear DNA is less susceptible to viruses
than circular DNA.
C. Since mitochondria and chloroplasts have
circular DNA, nuclear DNA had to be linear.
D. Replication can begin from multiple sites
on a linear DNA, allowing for rapid replication
and relieving the evolutionary pressure for a
streamlined genome.
