Sequence homology between the RSV-A2 N-protein gene and the PCR products amplified from fetal and offspring tissues exposed to the virus in utero.

Legend:% Identity: Extent to which two nucleotide sequences are invariant.Bit score: Value derived from the raw alignment score (sum of substitution and gap scores), in which the statistical properties of the scoring system used have been taken into account allowing for comparisons across sequence analysis programs.E-value (expectation value): Probability of a false positive based on the bit score.Length: Length of target sequence homologous with unknown sequence.
