in contrast to the changes in thymidine kinase ( schneider , e. , muller , b. and schindler , r. ( 1983 ) biochim . biophys . acta 741 , 77-85 ) , the decrease of polymerase alpha during entry of cells into proliferative quiescence thus appears to be under rather relaxed control , while after return of arrested cells to the permissive temperature the increase in polymerase alpha is tightly coupled with reentry of cells into s phase .
