title: Ribonucleic acid-dependent deoxyribonucleic acid polymerase in visna virus.
abstract: A ribonucleic acid-dependent deoxyribonucleic acid polymerase was found in virions of visna virus. The enzyme product was resistant to ribonuclease and alkaline hydrolysis but susceptible to the digestion of deoxyribonuclease.
