Polymer-assisted compaction of dna
Did you know?
DNA condensation refers to the process of compacting DNA molecules in vitro or in vivo. Mechanistic details of DNA packing are essential for its functioning in the process of gene regulation in living systems. Condensed DNA often has surprising properties, which one would not predict from classical concepts of dilute solutions. Therefore, DNA condensation in vitro serves as a model system for … WebAbstract. PEGylated poly-L-lysine DNA nanoparticles are composed of plasmid DNA compacted with poly-L-lysine conjugated with polyethylene glycol (PEG). They are soluble and stable in saline and tissue fluids, transfect nondividing cells, display minimal toxicity, and are effective in vivo and in humans. Moreover, they are easy to prepare in a ...

If stretched to its full length, the DNA molecule of the largest human chromosome would be 85mm. Yet during mitosis and meiosis, this DNA molecule is compacted into a chromosome approximately 5µm long. Although this compaction makes it easier to transport DNA within a dividing cell, it also makes DNA less …
