Categories: Disambiguation Mathematics is the study of quantity, structure, space and change. ... In mathematics, the complex numbers are an extension of the real numbers by the inclusion of the imaginary unit i, satisfying . ... In mathematics, the complex conjugate of a complex number is given by changing the sign of the imaginary part. ... In mathematics, in particular field theory, the conjugate elements of an algebraic element α, over a field K, are the (other) roots of the minimal polynomial PK,α(t) of α over K. If K is given inside an algebraically closed field C, then the conjugates can be taken inside... In mathematics, differential topology is the field dealing with differentiable functions on differentiable manifolds. ... This is a glossary of some terms used in Riemannian geometry and metric geometry — it doesnt cover the terminology of differential topology. ... Group theory is that branch of mathematics concerned with the study of groups. ... In mathematics, the elements of any group may be partitioned into conjugacy classes; members of the same conjugacy class share many properties, and study of conjugacy classes reveals many important features of a groups structure. ... In group theory, the conjugate closure of a subset S of a group G is the subgroup of G which is generated by the elements of S and their conjugates SG = {x ∈ G | there exists g ∈ G and s ∈ S such that x = g−1sg}, The conjugate closure of S... A Latin square is an n × n table filled with n different symbols in such a way that each symbol occurs exactly once in each row and exactly once in each column. ... Chemistry (in Greek: χημεία) is the science of matter and its interactions with energy and itself (see physics, biology). ... In the Brønsted-Lowry (protonic) theory of acids and bases, a conjugate acid is the acid member, HX, of a pair of two compounds that transform into each other by gain or loss of a proton. ... Broadly conceived, linguistics is the scientific study of human language, and a linguist is someone who engages in this study. ... In linguistics, conjugation is the creation of derived forms of a verb from its principal parts by inflection (regular alteration according to rules of grammar). ... Main article: Life There are many universal units and common processes that are fundamental to the known forms of life. ... Reproduction is the creation of one thing as a copy of, product of, or replacement for a similar thing, e. ... Space-filling model of a section of DNA molecule Deoxyribonucleic acid (DNA) or deoxyribose nucleic acid is a nucleic acid that contains the genetic instructions specifying the biological development of all cellular forms of life (and many viruses). ... Cells in culture, stained for keratin (red) and DNA (green) The cell is the structural and functional unit of all living organisms, sometimes called the building blocks of life. ...

Bacterial conjugation is the often regarded as the bacterial equivalent of sexual reproduction or mating; however it is not actually sexual as it does not involve the fusing of gametes and the creation of a zygote, it is merely the exchange of genetic information. ...
