Eukaryotic chromosomes are located within the nucleus, whereas prokaryotic chromosomes are located in the nucleoid. In eukaryotic chromosomes, DNA is wound around histone proteins, and then, it is further compacted by supercoiling and folding.


In prokaryotic chromosomes, DNA is supercoiled and compacted by nucleoid-associated proteins. Here is a basic summary of the key differences between eukaryotic and prokaryotic chromosomes. These figures illustrate the compaction of the eukaryotic chromosome. Improve this page Learn More. Skip to main content. Search for:. Practice Question Figure 1. Show Answer What advantages might there be to having them occur together? Compartmentalization enables a eukaryotic cell to divide processes into discrete steps so it can build more complex protein and RNA products.


But there is an advantage to having a single compartment as well: RNA and protein synthesis occurs much more quickly in a prokaryotic cell. Try It. Did you have an idea for improving this content? Licenses and Attributions. The DNA found in the linear chromosomes within the nucleus is tightly coiled and packaged around special proteins called histones - as shown below. Interestingly, circular chromosomes are also found in mitochondria and chloroplasts.


They both use their own DNA to make some proteins needed for their function. This gives evidence for the theory that mitochondria and chloroplasts originated from prokaryotic cells that were engulfed by a larger cell.


Prokaryotes Bacteria are prokaryotes.
