Transposition

Transposition refers to the process of changing the order or position of something, particularly in the context of mathematics, music, genetics, and medicine.

Mathematics

In mathematics, transposition involves changing the order of elements in an equation or matrix. For example, in the equation a + b = c, transposing 'b' to the other side of the equation gives a = c - b. In the context of matrices, transposition refers to the interchange of rows and columns in a matrix.

Music

In music, transposition refers to the process of moving a collection of notes (a melody, a chord, a whole musical piece) up or down in pitch by a constant interval. For example, the melody C-D-E could be transposed up by a major third to E-F#-G#.

Genetics

In genetics, transposition refers to the movement of genes or sequences of DNA from one location in the genome to another. This process is facilitated by enzymes known as transposases. Transposition can result in significant genetic changes, including mutations and the creation of new genes.

Medicine

In medicine, transposition often refers to a type of congenital heart defect known as Transposition of the great arteries (TGA), where the two main arteries leaving the heart are reversed in position, or "transposed".
