A
chromosome which, when
stained, produces a banded pattern of alternating light and dark segments (also called a
harlequin pattern). It is made by treating a cell with
5'-bromodeoxyuridine; the
chemical incorporates into the cell's
DNA and when stained is lighter than the DNA around it. (A chromosome is made up of DNA).
