Does a eukaryotic have a dna
WebEukaryotic DNA is bound to basic proteins known as histones to form structures called nucleosomes. The chromatin (the complex between DNA and proteins) may undergo some chemical modifications, so that the DNA may be able to slide off the proteins or be accessible to the enzymes of the DNA replication machinery. WebProkaryotic cells also have a lot of DNA, but the molecules don’t need to be packaged up quite as tightly as they do in eukaryotic cells. E. coli has around 1.6mm, or 4 million base pairs, of DNA—compare this to the 2m …

WebSo far, human and other eukaryotic transcription factors don't seem all that different from the transcription factors we've seen in bacteria. They bind DNA and make it easier or harder for RNA polymerase to do its job—just like the lac repressor protein of E. coli In general, this is a pretty good takeaway.
WebJan 26, 2024 · The main difference between prokaryotes and eukaryotes is that eukaryotes contain membrane-bound organelles, and prokaryotes do not. This means that prokaryotes do not have a nucleus; instead, they keep their DNA in a cell region called the nucleoid.
