Abstract:Normal cellular function relies on the efficient and accurate readout of the genetic code. Single-molecule experiments show that transcription and replication are highly intermittent processes that are frequently interrupted by polymerases pausing and reversing directions. Although intermittent dynamics in replication are known to result from proofreading, their origin and significance during transcription remain controversial. Here, we theoretically investigate transcriptional fidelity and show that the kinet…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
