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.
Okazaki fragments are then synthesized via extension of these RNA primers by DNA polymerase. An important consequence of such RNA priming is that newly synthesized Okazaki fragments contain an RNA-DNA joint, the discovery of which provided critical evidence for the role of RNA primers in DNA replication.ction of topoisomerases during DNA replication. (A) As the two strands of template DNA unwind, the DNA ahead of the replication fork is forced to rotate in the opposite direction, causing circular molecules to become twisted around themselves.
