Topoisomerase |
True or False: Single DNA molecules are said to be antiparallel when they are lined up next to each other but oriented in opposite directions |
True |
Leading strand |
1. only one primer needed 2. made continuously 3. daughter strand elongates toward replication fork |
Lagging strand |
1. made in segments 2. multiple primers needed 3. daughter strand elongates away from replication fork |
