Evolution of defective-interfering double-stranded RNAs of the yeast killer virus. 1979

W P Kane, and D F Pietras, and J A Bruenn

We have characterized by T1 fingerprint analysis several defective interfering (DI) double-stranded RNAs of the simple yeast virus ScV. A common sequence of about 0.5 to 0.6 kilobase pairs, including both 3' termini of the parental RNA, was present in each DI RNA. Several DI RNAs had novel T1 oligonucleotides not present in their parental RNA.

UI	MeSH Term	Description	Entries
D009843	Oligoribonucleotides	A group of ribonucleotides (up to 12) in which the phosphate residues of each ribonucleotide act as bridges in forming diester linkages between the ribose moieties.
D003673	Defective Viruses	Viruses which lack a complete genome so that they cannot completely replicate or cannot form a protein coat. Some are host-dependent defectives, meaning they can replicate only in cell systems which provide the particular genetic function which they lack. Others, called SATELLITE VIRUSES, are able to replicate only when their genetic defect is complemented by a helper virus.
