Comparison of Genetic Information In Eukaryotes And Prokaryotes

As for organisms in the world from humans to the smallest microbe, they directly reflect upon biodiversity, in respect to the appearance, size and expression. The reason behind this is caused by the genetic material found in each and every cell that composes each organism. Given that there are two types of cell organizations found in life, comparison of both ‘eukaryote’ and ‘prokaryote’ genomes will provide a better understanding for such diversity. ‘karyote’ refers to the nucleus, and also ‘pro’ means ‘absence’ and ‘eu’ means ‘presence’. Therefore the words prokaryote and eukaryote reflect upon the individual cell organization. In contrast, the both organizations show discrepancies as well as similarities which ultimately make them unique to one and other.

The aim of this essay is to compare and contrast the genomes in eukaryotes and prokaryotes according to the perspective of Cell biology (The science that studies about cells). This comparison is conducted on genetic material, in respect to their location, size, expression, structure, architecture as well as number.

Genome Location

The location of genomes in both prokaryotes and eukaryotes show major discrepancies because they have different levels of cell organization. Due to the simplicity of the prokaryotes, they lack membrane bound organelles such the nucleus. Therefore, genomes of the prokaryotes reside as irregular Protein and deoxyribos nucleic acid (DNA) complex in cytosol (liquid portion of cytoplasm). This area of the cytoplasm is defined as the ‘nucleoid’ (Bauman.R 2004). Unlike Eukaryotes, it does not possess a nuclear envelope.

In conclusion, the above comparison draws out few facts that should be taken into account for a better understanding of the genomes of the two organizations. Above all, the fact that the eukaryotes show similarities to prokaryotes could mean that they derived from prokaryotes initially, and then became more complex as they advanced. This fact also supports the Endosymbiosis theory. And the eukaryotic genomes are larger and more repetitive, which makes them less productive than the prokaryotic genes. But considering by the quantity of the genes, eukaryotes are effective. In the perspective of expression, the complex eukaryotes have to go through physical borders and take more time and energy to express its genes. Due to the simplicity of the prokaryotes, their genomes highly efficient much more simple and they are stronger than what people think.
