Characteristics of eukaryotic stayinfiji.com DNA compared to prokaryotic DNA

Prokaryotic cell are recognized to be much less facility than eukaryotic cells due to the fact that eukaryotic cells are taken into consideration to be present at a later suggest of evolution. That is probable that eukaryotic cells developed from prokaryotic cells. Distinctions in intricacy can be checked out at the moving level.

You are watching: Which of the following is characteristic of prokaryotic genomes but not eukaryotic genomes?

The solitary characteristic the is both necessary and also sufficient to define an organism together a eukaryotic stayinfiji.com is a nucleus surrounding by a atom envelope through nuclear pores. All extant eukaryotes have actually cells v nuclei; many of a eukaryotic stayinfiji.com cell’s hereditary material is had within the nucleus. In contrast, prokaryotes DNA is not included within a nucleus, however rather is attached to the plasma membrane and also contained in the kind of a nucleoid, one irregularly-shaped an ar that is no surrounded by a nuclear membrane.

Figure (PageIndex1): Cellular place of eukaryotic and prokaryotic DNA: eukaryotic stayinfiji.com DNA is save on computer in a nucleus, whereas prokaryotes DNA is in the cytoplasm in the kind of a nucleoid.

Eukaryotic DNA is packed right into bundles that chromosomes, every consisting that a direct DNA molecule coiled around simple (alkaline) proteins called histones, which wind the DNA into a an ext compact form. Prokaryotic DNA is uncovered in circular, non-chromosomal form. In addition, prokaryotes have actually plasmids, i beg your pardon are smaller pieces of circular DNA that have the right to replicate independently from prokaryotes genomic DNA. Due to the fact that of the direct nature of eukaryotic stayinfiji.com DNA, repeating non-coding DNA sequences called telomeres are present on either finish of the chromosomes as protection from deterioration.

Mitosis, a procedure of nuclear department wherein replicated chromosomes room divided and also separated using facets of the cytoskeleton, is universally existing in eukaryotes. The cytoskeleton has structural and motility components called actin microfilaments and also microtubules. All extant eukaryotes have actually these cytoskeletal elements. Prokaryotes meanwhile undergo binary fission in a process where the DNA is replicated, then separates to 2 poles that the cell, and, finally, the cell fully divides.

A major DNA difference between eukaryotes and also prokaryotes is the presence of mitochondrial DNA (mtDNA) in eukaryotes. Since eukaryotes have mitochondria and prokaryotes carry out not, eukaryotic cells save mitochondrial DNA in addition to DNA contained in the nucleus and ribosomes. The mtDNA is created of significantly fewer base pairs than nuclear DNA and also encodes only a few dozen genes, relying on the organism.
