WebSequence motifs that give driving forces to initiate DNA replication. The replication origin could be defined as the initiating point that generates a replication bubble. Most of the chromosomes of prokaryotic cells or bacteria, including E. Coli, have a supercoiling circular form. Multiple super-helical loops help compact the bacterial genome ... WebThe laboratory you joined is studying the life cycle of an animal virus that uses a circular, double-stranded DNA as its genome. Your project is to define the location of the origin(s) of replication and to determine whether replication proceeds in one or both directions away from an origin (unidirectional or bidirectional replication).
