Is histone acidic or basic
WebCorrect option is C) Histones are small proteins which have a high amount of basic amino acids (arginine and lysine) and are called basic proteins. Each nucleosome consists of a segment of DNA wrapped in sequence around eight histone protein core. So, the correct answer is 'Basic proteins'. Was this answer helpful? 0 0 Similar questions WebAll four of the core histone amino acid sequences contain between 20 and 24% of lysine and arginine and the size or the protein ranges between 11400 and 15400 Daltons, making them relatively small, yet highly positively charged proteins. ...
