The germ line limited M element of Tetrahymena is targeted for elimination from the somatic genome by a homology-dependent mechanism.

abstract：:A UCSD Pascal program was developed which can analyze nucleic acid dot matrices of up to 9500 X 9500 in size on the Apple II computer. Although matrices of such size consume large amounts of computer memory, this program minimizes these problems by analyzing only small strips of the matrix at a time, and then transfer...
