Describe how the structure of a prokaryotic chromosome differs from the structure of a eukaryotic chromosome.

In prokaryotes, the circular chromosome is held in the cytoplasm in a region called nucleoid whereas in eukaryotes chromosomes are stored within a structure called the nucleus.

Prokaryotic chromosome comprises only a single origin of replication whereas the eukaryotic chromosome carries multiple origins of replication.

Prokaryotic chromosome consists of covalently closed (loop) circular DNA whereas the eukaryotic chromosome consists of linear DNA not circular.

Answer:

Prokaryotes and Eukaryotes are two important forms of living organisms. These two domains posses some similarities as well as dissimilarities. they differentiate on the structure of a chromosomes in prokaryotes and eukaryotes, that are as following:

In prokaryotes, the chromosome is circular and located in a region called the nucleoid present in the cytoplasm. In comparison, in eukaryotes all chromosomes of the cell are contained inside a structure called the nucleus.
DNA is not attached with histone protein in prokaryotes while DNA is attached with histone proteins in Eukaryotes.
In prokaryotes, there is only one origin of replication but in eukaryotes there are many origin of replication.

Thus, the structural difference in prokaryotic chromosome and eukaryotic chromosome is explained.
