The direct repeat 1 (dr1) element is an RNA element com-

monly found in the 3’ UTR of Avian sarcoma, Rous sar-

coma and Avian leukosis viruses (Alpharetroviruses and

Avian type C retroviruses). dr1 is required for efficient vi-

ral replication and is thought to be involved in genomic

RNA packaging although this may not be its only role.[1]
