Comparison of genetic information in eukaryotes and prokaryotes As for the world's organisms, from humans to the smallest microbe, it directly affects biodiversity, with respect to appearance , size and expression. The reason for this is caused by the genetic material present in every cell that makes up each organism. Since there are two types of cellular organizations in life, comparing the genomes of “eukaryotes” and “prokaryotes” will provide a better understanding of this diversity. 'karyote' refers to the core, and 'pro' also means 'absence' and 'eu' means 'presence'. Therefore the words prokaryote and eukaryote reflect individual cellular organization. On the contrary, both organizations exhibit discrepancies and similarities that ultimately make them unique from each other. The purpose of this essay is to compare and contrast genomes in eukaryotes and prokaryotes from the perspective of cell biology (The science that studies cells). This comparison is conducted on the genetic material, with respect to their position, size, expression, structure, architecture and number. Location of the Genome The location of genomes in both prokaryotes and eukaryotes shows important discrepancies because they have different levels of cellular organization. Due to the simplicity of prokaryotes, they lack membrane-bound organelles such as the nucleus. Therefore, prokaryote genomes reside as irregular complexes of proteins and deoxyribonucleic acid (DNA) in the cytosol (liquid portion of the cytoplasm). This area of ​​the cytoplasm is defined as the 'nucleoid' (Bauman.R 2004). Unlike eukaryotes, it does not have a nuclear envelope. A...... middle of the paper ...... In conclusion, from the above comparison some facts emerge that should be taken into consideration for a better understanding of the organism's genomes of the two organizations. Most importantly, the fact that eukaryotes show similarities to prokaryotes could mean that they initially arose from prokaryotes, then became more complex as they advanced. This fact also supports the theory of endosymbiosis. Additionally, eukaryotic genomes are larger and more repetitive, making them less productive than prokaryotic genes. But considering the quantity of genes, eukaryotes are effective. From the expression perspective, complex eukaryotes must cross physical boundaries and spend more time and energy expressing their genes. Due to the simplicity of prokaryotes, their highly efficient genomes are much simpler and stronger than we think.
