Gender binary question society's role in constructing gender. Fausto-Sterling indicates that modern practitioners encourage the idea that gender is a cultural construct and concludes that, "we are moving from an era of sexual dimorphism to one of variety beyond the number 2." Gender binary The gender binary, also referred to as gender binarism (sometimes shortened to just binarism), is the classification of sex and gender into two distinct, opposite and disconnected forms of masculine and feminine. Gender binary is one general type of a gender system. Sometimes in this binary model, "sex", "gender" and "sexuality" are assumed by default to align. For
Transfer DNA binary system Transfer DNA binary system A transfer DNA (T-DNA) binary system is a pair of plasmids consisting of a binary plasmid and a helper plasmid. The two plasmids are used together (thus "binary") to produce genetically modified plants. They are artificial vectors that have both been created from the naturally occurring Ti plasmid found in "Agrobacterium tumefaciens". The binary vector is a "shuttle vector", so-called because it is able to replicate in multiple hosts ("E. coli" and "Agrobacterium tumefaciens"). Systems in which T-DNA and vir genes are located on separate replicons are called T-DNA binary systems. T-DNA is located on the
