WebFluctuations between open and closed chromatin may contribute to the discontinuity of transcription, or transcriptional bursting. Other factors are probably involved, such as the association and dissociation of transcription factor complexes with chromatin. Web17 de nov. de 2014 · We have suggested two hypotheses for the evolution of open and closed mitosis involving adaptive processes. With the acquisition of additional data it should be possible to determine the validity of these scenarios, and it will be interesting to explore the implications of alternative hypothesis as well.
