4) We discussed three models of DNA replication: conservative, semi-conservative, and dispersive. Briefly explain why rolling circle replication is not considered an example of any of these types of replication (hint: think about the products or daughter molecules predicted by each model, and compare them to the products of rolling circle replication). Please note that the question does NOT ask you to describe the process of rolling circle replication, and doing so will NOT earn you any additional credit. (3 points)
