Eukaryotic chromosome have a different shape from the prokaryotic chromosome as the bacterial chromosome is circular and less complex due to no histone found in prokaryotes as we see in the eukaryotic chromosome. SIze of the bacterial or prokaryotic chromosome is also small and not found in condensed form as these cells carry less genetic information than eukaryotic cells.

Relative time of divergence from a common ancestor can be estimated by:.
igomit [66]

The relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.

<h3>What is sequence homo-logy?</h3>

In molecular biology, sequence homo-logy means the degree of similarity between sequences due to a common ancestor.

A sequence is a given fragment of a single DNA strand where nucleotides are arranged in a specific linear order.

Divergence or separation between lineages is directly proportional to the level of sequence homo-logy.

In conclusion, the relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.
