All cells, whether prokaryotic or eukaryotic, have a membrane that envelops the cell, regulates what moves in and out (selectively permeable), and maintains the electric potential of the cell. Inside the membrane, the cytoplasm takes up most of the cell's volume. Except red blood cells, which lack a cell nucleus and most organelles to accommodate maximum space for hemoglobin, all cells possess Webb14 apr. 2024 · In this study, the authors reveal that the basic domain of TRF2 (TRF2B) and RAP 1 cooperate to repress HDR at telomeres and prevent formation ultrabright telomere structures.
