Question

If DNA is negatively charged, how is the balaance made in the nucleus? Also, does DNA have it's own pH?

Answer 1

• The nucleus of a cell typically holds DNA, proteins, RNA, and other important chemicals! The DNA is negatively charged because of the presence of negatively charged phosphate group.
• Most of the proteins are negatively charged but the proteins like histones contain positively charged amino acid residues lysine and arginine which makes them positively charged that makes the balance in nucleus.
• DNA by itself doesn't have a pH. A solution of DNA would have a pH depending on the amount of DNA in the solution. If DNA has Low pH indicates that the solution DNA is in is acidic.
