What are the functions of the following eukaryotic cell structures: endoplasmic reticulum, Golgi complex, and lysosomes? Calculate the amount of time it would take a cell of Escherichia coli (1 x 2 mm) swimming at maximum speed (60 cell lengths per second) to travel all the way up a 3-cm-long capillary tube containing a chemical attractant. A structure commonly seen in circular DNA during replication is the theta structure. Draw a diagram of the replication process and show how a theta structure could arise.
