Web9 jan. 2024 · How is DNA packaged in the cell? Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Nucleosomes fold up to form a 30-nanometer chromatin fiber, which forms loops … WebDNA packaging is an important process in the living cell. A large amount of DNA is tightly packed in the small nucleus of every cell by DNA packaging. During DNA packaging, DNA is wrapped around histones. Histones are proteins that allow DNA to be tightly packaged into units called nucleosomes. Each nucleosome is composed of DNA that is …
