abstract：:The measles virus (MV) phosphoprotein (P) gene encodes three proteins, P, C, and V. The V protein is synthesized by pseudo-templated transcription, also designated as RNA editing: during P gene transcription one G residue is inserted at a defined position in about 50% of the mRNAs. To study the importance of sequence ...
