linker

(cell and molecular biology) A short, synthetic deoxyribonucleic acid (DNA) molecule that contains the recognition site for a specific restriction endonuclease. Also known as linker. A segment of DNA to which lysine-rich histone is bound and which connects the adjacent nucleosomes of a chromosome.

A utility program that links a compiled or assembled program to a particular environment. Also known as a "link editor," the linker unites references between program modules and libraries of subroutines. Its output is a load module, which is executable code ready to run in the computer. See executable code and bind.
