Real image of DNA molecules being copied in human cells, visualized by immunofluorescence microscopy. The yellow arrows mark where replication begins, and the white arrows indicate the direction ...
Each of us has enough DNA to reach from here to ... opening up chromatin fibers and/or removing histones transiently to permit transcription and replication to proceed. Generally speaking, there ...
Old histones are recycled during DNA replication, therefore providing a blueprint for the duplication of their modifications following DNA replication. Positive-feedback loops and cooperativity ...
Scientists have sorted out another piece of the DNA replication puzzle by showing what might happen to histones through the process of unwinding DNA. The linkurl ...
The mechanism of a peculiar type of heterochromatin, used by embryonic stem cells to silence 'parasitic' DNA-elements within the context of their highly dynamic pluripotent chromatin. Disclaimer ...
