Negative feedback in NO/cGMP signalling.

abstract：:The process of information exchange between two homologous DNA duplexes is known as homologous recombination (HR) or double-strand break repair (DSBR), depending on the context. HR is the fundamental process underlying the genome shuffling that expands genetic diversity (for example during meiosis in eukaryotes). DSBR...
