Fluorescence resonance energy transfer has been used to explore the interactions between DNA polymerases, sliding clamps and clamp loaders as DNA is replicated in human cells.
When a protein involved in DNA repair malfunctions, it can anneal RNA molecules to DNA molecules, creating hybrids that increase the frequency of mutations in the DNA.

Utilizing a conserved mechanism, a ribosome can initiate translation from a site within the insulin receptor mRNA to maintain protein synthesis even when standard mechanisms of initiating translation have been inhibited by stress.
A cell-free system combined with cell-based assays elucidate the biochemical mechanism of signal transduction mediated by the mitochondrial protein MAVS and delineates the role of ubiquitin E3 ligases in antiviral innate immune responses.

The Chd1 motor protein performs two functionally distinct ATP-dependent activities, nucleosome assembly and chromatin remodeling, to generate periodic arrays of nucleosomes.
During meiosis, budding yeast use a checkpoint involving the protein Mec1 to prevent the formation of double-strand breaks in DNA that has not completed replication.
