a declining rate of mrna synthesis can be accommodated in a two-cell-division model , when synthesis halves at each cell division and cell times are essentially the same as above , but mrna half-life is either 9h in the basophilic and polychromatophilic erythroblasts and 17h in the later cells , or 10h in the basophilic erythroblasts and polychromatophilic erythroblasts and 14.5h in later cells .
