chromatin will synthesize dna for a much longer time than isolated nuclei so that larger amounts of dna can be synthesized in vitro in addition , although chromatin has its own endogenous ability to synthesize dna , it is markedly stimulated by the presence of exogenously added hela cell dna polymerase alpha , beta , and gamma , and , thus , may provide a new template system for the study of dna synthesis .
