Answer:
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 averaging 300 nanometers in length.
Explanation:
Histones help to package chromosomal DNA inside microscopic nuclei. These are positively charged proteins that bind to negatively charged DNA to form complexes known as nucleosomes.
What are nucleosomes?
A nucleosome is made up of about 150 base pairs of DNA rolled up around a core of histone proteins.
The nucleosomes recurrently fold in on themselves to tighten and condense the packaged DNA when forming a chromosome.
Histones help to package chromosomal DNA inside microscopic nuclei. These are positively charged proteins that bind to negatively charged DNA to form complexes known as nucleosomes.
Thus, in this way, DNA gets stored.
