In general, eukaryotic cells contain a lot more genetic material than prokaryotic cells. Similarities Between Plasmid and Chromosome 5. This is possible because prokaryotic cells lack a nuclear membrane, so transcription and translation occur in the same region. Each eukaryotic chromosome contains a linear DNA with two ends. Eukaryotic chromosomes are separated from the cytoplasm by the nuclear membrane. In addition, the telomeresrepeating DNA sequences at the ends of each chromosomelimit the number of times a cell can divide before it dies or becomes senescent. Both undergo DNA methylation for the structural regulation of gene expression. Prokaryotic chromosomes are primarily haploid while eukaryotic chromosomes are primarily diploid, Eukaryotic chromosome DNA replication occurs during S phase of the cell cycle while prokaryotic chromosome DNA replication occurs at the beginning of cell division, The negative charge of eukaryotic chromosomes are nullified by histone while for prokaryotic chromosomes are nullified by a magnesium ion, Eukaryotic chromosomes are coded for a large number of proteins while prokaryotic chromosomes are coded for few proteins, Eukaryotic chromosomes are enclosed in the nucleus while prokaryotic chromosomes occupy freely the center of the cell, Eukaryotic chromosomes have no direct contact with cytoplasm while prokaryotic chromosomes have direct contact with cytoplasm from inside, Prokaryotic chromosomes have single-origin while eukaryotic chromosomes have several origins, Eukaryotic chromosomes have both telomere and centromere while prokaryotic chromosomes tend to lack, Eukaryotic chromosomes have homologous chromosomes while prokaryotic chromosomes do not have, Prokaryotic chromosomes have organized gene structure into operons while eukaryotic chromosomes have genes that are regulated by individual structures, Prokaryotic chromosomes are present in prokaryotes while eukaryotic chromosomes are present in eukaryotes, Both have a similar chemical composition and structural organization of DNA, Both are facilitated by translation and transcription. Since eukaryotic cells typically have multiple linear chromosomes, capped with telomeres, eukaryotic DNA replication and cell division (mitosis and meiosis) are a bit more complicated. In eukaryotes, the association of DNA with the histone produces distinct structural repeats called nucleosomes. The nucleoid association helps the chromosome to form a loop structure for packing. Eukaryotes reproduce sexually through meiosis, which allows for genetic variance.
