Molecular biology: DNA packaging supports cell division

WebEukaryotes, whose chromosomes each consist of a linear DNA molecule, employ a complex type of packing strategy to fit their DNA inside the nucleus (Figure 4). At the most basic level, DNA is wrapped around … WebIn a cell, DNA does not usually exist by itself, but instead associates with specialized proteins that organize it and give it structure. In eukaryotes, these proteins include the histones, a group of basic (positively charged) proteins that form “bobbins” around which negatively charged DNA can wrap.In addition to organizing DNA and making it more … WebThe DNA in prokaryotic cells is significantly different from the DNA found in eukaryotic cells “Prokaryote” means “before the nucleus” The DNA is double-stranded; Prokaryotes possess a single, circular chromosomal DNA molecule.
