Q: compare and contrast the prokaryotic and eukaryotic genomes
The eukaryotic genome is diploid but the prokaryotic genome is haploid. The eukaryotic genome has multiple origins of replication but the prokaryotic genome has only one origin of replication. The eukaryotic genome may have more than one chromosome but the prokaryotic genome has only one chromosome. The chromosomes in eukaryotic cells are linear but the chromosome in prokaryotic cells is circular. The eukaryotic genome size is much larger (10 to 100000 million bases) but the prokaryotic genome size is much smaller (0.6 to 10 Mb). The eukaryotic gene length is around one an a half times as long as the prokaryotic gene length. The eukaryotic genome is much more complex, with distinct regions such as the centromere and the telomere, whereas the prokaryotic genome is much simpler with no distinct regions. In the eukaryotic genome, the DNA is bound to histone proteins to form nucleosomes, which wind around each other to form chromosomes, but in the prokaryotic genome, DNA is bound to nucleoid associated proteins to form a DNA-protein complex. The eukaryotic genome is enclosed within a true membrane bound nucleus but the prokaryotic genome does not have a true nucleus, only a region called the nucleoid.

Prokaryotes Vs Eukaryotes
While eukaryotic cells and prokaryotic cells have some characteristics in common, they diverged from their common ancestor billions of years ago, thus accounting for significant differences in overall structure and function. Here we will go over them....

Eukaryotic And Prokaryotic Cells
What are Eukaryotic and Prokaryotic cells??? They are the tiny little building blocks of life and sometimes death! Eukaryotic cells are what make up humans, animals, and plants. They do everything from constructing us as babies with DNA to making...

Why Are Genomes So Large?
KEY TERMS:The C-value is the total amount of DNA in the genome (per haploid set of chromosomes). The C-value paradox describes the lack of relationship between the DNA content (C-value) of an organism and its coding potential. KEY CONCEPTS: There is...
