title: Involvement of directly repeated sequences in the generation of deletions of the avian sarcoma virus src gene.
abstract: Nucleotide sequence analysis of two molecular clones of transformation-defective avian sarcoma virus indicate that direct repeated sequences of 6 and 20 nucleotides are involved in the formation of the src deletions in these clones.
