title: Frequent polymerase errors observed in a restricted area of clones derived from the attachment (G) protein gene of respiratory syncytial virus.
abstract: Sequence analysis of a large number of clones derived from the carboxy-terminal one-third of the attachment (G) protein gene of subgroup A respiratory syncytial viruses revealed a region very prone to polymerase errors which resulted mainly in frameshifts because of the insertion or deletion of adenosine residues in some but not all runs of such residues. Such mutations were detected in 14% of clones derived from mRNA, 58% of clones derived from genomic-sense RNA, and 50% of clones derived from in vitro-transcribed RNA. This phenomenon appears to be dependent on the template sequence.
