Instability of large direct repeats in retrovirus vectors.

AUTOR(ES)
RESUMO

Retrovirus vectors were constructed with large (0.85- to 1.3-kilobase-pair) direct repeats in their genomes. Deletions involving the direct repeats occurred at a high frequency. Deletions occurred both when the direct repeats were in tandem and when they were separated by additional sequences. These deletions occurred during virus replication.
