How is dna arranged in a prokaryotic cell

Web26 sep. 2024 · Where is the DNA in a eukaryote? In eukaryotes, the cell’s genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes. How is DNA arranged in prokaryotic and eukaryotic cells? Prokaryotes contain a single, double-stranded circular chromosome. WebThe prokaryotic DNA is placed in the center of the cell and is called the nucleoid and does not have any nuclear membrane. The DNA has in general a charge which is negative inside the cells of bacteria and do lack the helical turns. The DNA is not nor overwound or under overwound but takes up the confirmation of being relaxed.
