(i think this question wasn’t really a question but i answered it anyway lol. i’m sorry that chemistry is hard. good luck!)
The proteins are called Histone proteins. Chromosomal DNA is packaged such that the strands of DNA are wound around histone proteins and fold into complex ways to form chromosomes. The histone proteins are positively charged proteins that strongly adhere to negatively charged DNA and form complexes called nucleosomes. Each nucleosome is composed of double-helical DNA wrapped.
Do you have a like text book for this for me to answer?
