Physical evidence for a Saccharomyces cerevisiae transposable element which carries the his4C gene.

Abstract

A Saccharomyces cerevisiae transposable element which carries the his4C structural gene and which is capable of transposition, excision, and mutator activity is described. Physical evidence is presented for transposition of the his4C deoxyribonucleic acid sequences to a new location in the genome and for precise excision of these transposed deoxyribonucleic acid sequences in spontaneous his4C- segregants.
