COMPARISION :

  • The structure and chemical composition of the DNA in both the eukaryotic and prokaryotic cells are different. 
  • The prokaryotic cells have no nucleus, no organelles and a very small amount of DNA. 
  • On the other hand, the eukaryotic cells have nuclei and cell organelles, and the amount of DNA present is large.
 SIMILARITIES AND DIFFERENCE:

  • In both prokaryotic and eukaryotic chromosomes, gene expression is facilitated through transcription and translation of genetic information in chromosomes.
  • In both Prokaryotes & Eukaryotes, chromosomal DNA undergoes DNA methylation resulting in the structural regulation of gene expression.
  •  The genetic material in both chromosomal groups contains coding as well as non-coding sequences.
  • prokaryotes DNA lacks transposons whereas the Eukaryotic DNA has transposons
  • In Prokaryotes DNA replication occurs in cytoplasm but in Eukaryotes DNA replication happens within the nucleus of the cell
