alpha-helix E of Spo0A is required for sigma(A)- but not for sigma(H)-dependent promoter activation in Bacillus subtilis [PDF]
, 2004 At the onset of endospore formation in Bacillus subtilis, the DNA binding protein Spo0A activates transcription from two types of promoters. The first type includes the spoIIG and spoIIE promoters, which are used by sigma(A)-RNA polymerase, whereas the ...

Polymerase Chain Reaction [PDF]
Journal of Investigative Dermatology, 2013 The advent of the polymerase chain reaction (PCR) radically transformed biological science from the time it was first discovered (Mullis, 1990). For the first time, it allowed for specific detection and production of large amounts of DNA. PCR-based strategies have propelled huge scientific endeavors such as the Human Genome Project.

A new contribution to Megasporoporia sensu lato: Six new species and three new combinations
Frontiers in Microbiology, 2022 Megasporoporia sensu lato has recently been intensively studied in China and South America, and four independent clades representing four genera have been recognized phylogenetically. In this study, more samples, mostly from subtropical and tropical Asia,

Proficient replication of the yeast genome by a viral DNA polymerase [PDF]
, 2016 DNA replication in eukaryotic cells requires minimally three B-family DNA polymerases: Pol α, Pol δ, and Pol ϵ. Pol δ replicates and matures Okazaki fragments on the lagging strand of the replication fork.
