Packet 3: Bonus 5
The minute (“my-NOOT”) virus of mice, or MVM, is commonly used as a model for gene expression, alternative splicing, and this process in parvoviruses. For 10 points each:
[10e] Name this genetic process in which a new DNA strand is generated from a pre-existing DNA template.
ANSWER: DNA replication [or genome replication; accept DNA synthesis; prompt on synthesis]
[10m] Since they possess linear genomes, termination of rolling replication in parvoviruses has to be induced via the formation of these structures. Pseudoknots are formed from the intercalation of two or more of these structures.
ANSWER: hairpins [or hairpin loops; accept RNA hairpins or DNA hairpins; accept stem-loops; accept rolling-hairpin replication or rolling-hairpin synthesis; prompt on RHR; reject “loops” or “DNA loops”]
[10h] Before being cleaved by NS1 and Cap, these molecules are generated by parvoviruses after iterations of rolling-hairpin replication. These molecules consist of multiple identical DNA sequences linked end-to-end.
ANSWER: concatemers [prompt on genome tetramers]
