This is leading to problems, however, as people plant inappropriate trees due to a false notion of what native means, good well-adapted trees that are non-native get overlooked, and homes built in existing native landscapes are subjected to dangerous fires.he concept and practice of using native trees in home and business landscapes in our region has some problems. By definition, a native plant is one that is living, growing, and reproducing naturally in a particular region. The key idea here is how we define a region.
The lagging strand replicates in small segments, called Okazaki fragments. These fragments are stretches of 100 to 200 nucleotides in humans (1000 to 2000 in bacteria) that are synthesized in the 5' to 3' direction away from the replication fork.
1 The separation of the two single strands of DNA creates a âYâ shape called a replication âforkâ. 2  The two separated strands will act as templates for making the new strands of DNA. 3  One of the strands is oriented in the 3â to 5â direction (towards the replication fork), this is the leading strand. Chunks of DNA, called Okazaki fragments, are then added to the lagging strand also in the 5â to 3â direction. 2  This type of replication is called discontinuous as the Okazaki fragments will need to be joined up later.
