Question 2 (Multiple Choice, Worth 4 Points)
The DNA structures of prokaryotic and eukaryotic cells share similarities and differences. One way in which they are the same is:

A. Both have sugar-phosphate backbones.
B. Most of the DNA is in the form of plasmids.
C. Both have a singular circular chromosome.
D. The DNA is packaged into several linear pieces.



Answer :

Final answer:

Prokaryotic cells have a singular circular chromosome, whereas eukaryotic cells have linear chromosomes, leading to differences in genome packaging and gene regulation complexity.


Explanation:

Prokaryotic cells have a single circular chromosome, while eukaryotic cells have linear chromosomes. An advantage of eukaryotic genome packaging is increased stability and protection for the DNA due to the complex structure. However, a disadvantage is that it can make gene expression regulation more complex compared to prokaryotes.
