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.
Primase adds RNA primers onto the lagging strand, which allows synthesis of Okazaki fragments from 5' to 3'. However, primase creates RNA primers at a much lower rate than that at which DNA polymerase synthesizes DNA on the leading strand. DNA polymerase on the lagging strand also has to be continually recycled to construct Okazaki fragments following RNA primers. This makes the speed of lagging strand synthesis much lower than that of the leading strand.
