What percentage of human DNA is the same as the DNA of other species?

Like, I hear human DNA is roughly 95 to 98% identical as that of chimpanzees (reports seem to vary). On that model, what percentage of human DNA the same as that of, for example, a rat, a cockroach, a bacterium or a sunflower?



Ideally I'd like a link to a website showing the percentage comparison to a few different species.What percentage of human DNA is the same as the DNA of other species?
My info is outdated - I'm only familiar with the human-mouse-rat comparison; other mammalian species were being sequenced. One third of the DNA, comprising 95% of the coding and regulatory regions, aligned between the three species.



The X chromosome is peculiar because the genes it carries tend to stay in place: a nice image of its rearrangements can be found at:

ETA: the chimpanzee genome has been sequenced in 2005 and the similarity rate with humans appears to be 98.94%. Previous studies only considered the better characterized coding regions, and therefore overestimated similarity.What percentage of human DNA is the same as the DNA of other species?
Well the fundamental structure of the animal cell is pretty much the same in all animals. Cell membranes, mitochondria, ribosomes, endoplasmic reticula, golgi bodies, basic enzymes for uptake of glucose, for transporting ions around etc. The only differences between animals are those that cause growth, differentiation and specialised functions such as hormonal pathways and hair and things that are different between species. Now taking that into account we're probably at least 60-70% the same as every other animal on the planet...chimpanzees we're about 0.5% different to if I remember correctly. Prokaryotes like bacteria will differ a little bit more to us than animals since they're quite simple little things and plants are generally a little bit more complex than animals. Plants have all the same stuff that animal cells have, but they also have cell walls, chloroplasts, vacuoles and the have a lot of cell to cell binding proteins so will differ from us, but since they're more complex it would be more appropriate to describe the percentage of their DNA is the same as ours and not the other way round.What percentage of human DNA is the same as the DNA of other species?
1%..if that
