Based on the nature of the interaction between DNA and histones, what is the most likely requirement for all DNA-binding proteins? Most DNA-binding proteins would have a strong positive charge. DNA-binding proteins must contain adenine. Most DNA-binding proteins would have a strong negative charge. Most DNA-binding proteins are restriction enzymes.

The correct answer is Most DNA binding protein would have strong positive charge.

Explanation:

DNA is the genetic material in most organism. DNA consist of nucleotides that contain a nitrogen base, deoxyribose sugar and phosphate group. The phosphate group is highly reactive and contain negative charge.

Most DNA binding protein such as Helix turn helix, Leucine zipper, Zinc finger Interracts with the negatively charged phosphate group by the positive charge that they contain. This positive charge facilitates their interraction with negatively charged DNA molecule.
