True or False 1. There can be a quantitative determination of the degree of supercoiling in a DNA sample. 2. Topoisomerases can cut phosphodiester bonds and the DNA ligases will have to seal the nicks whenever there is a need to relieve the supercoiling. 3. Histone proteins are able to associate with DNA segments because of the anionic nature of the amino acids arg and lys.
