DNA is a central topic in biology courses because it is crucial to an understanding of modern genetics. Many instructors introduce the topic by means of a sanitized retelling of the history of the discovery of the structure of DNA by James Watson and Francis Crick. Historical research since 196...
CRISPR-Cas systems and IS200/IS605 transposon-associated TnpBs have been utilized for the development of genome editing technologies. Using bioinformatics analysis and biochemical experiments, here we present a new family of RNA-guided DNA endonucleases.
Design, characterization and structure–function analysis of novel antimicrobial peptides based on the N-terminal CATH-2 fragment Article Introduction The emergence of multidrug-resistant bacteria has created a need to develop novel classes of antibiotics to circumvent them1. As part of these efforts,...

Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.
