The transcription machinery used to regulate gene expression and self-renewal in human embryonic stem cells is different from that found in other cells.

A DNA–protein complex can find target sequences of bases in another DNA molecule by sliding along it.

A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.

Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

Experiments in mice have shown than an enzyme that repairs broken DNA inside the nucleus also has a central role in the innate immune system because it is able to detect foreign DNA outside the nucleus.

A bacterial protein can be programmed with short RNA molecules to stimulate genome editing at specific sites in human cells.

Islands of non-methylated DNA are shown to perform a similar epigenetic role in many different vertebrate species.
