Initiation of DNA synthesis by the avian oncornavirus RNA-directed DNA polymerase: tryptophan tRNA as the major species of primer RNA.

AUTOR(ES)
RESUMO

The major species of primer RNA required for the initiation of DNA synthesis by the Rous sarcoma virus RNA-directed DNA polymerase can be aminoacylated by tryptophan. Furthermore, an intact 3' terminus is required for the primer to function in the initiation of DNA synthesis.
