Vascular spasms are sudden, brief tightening of the muscle cells inside the walls of a blood vessels. It is the first response as the blood vessels constrict to allow less blood to be lost.

Basic amino acids have a positive charge and acidic amino acids have a negative charge. DNA also has negative charge because of the phosphate group in nucleotides. So they have opposite charges and can form ionic bonds.
Hope this helps:)
