Part 1 Climate Change and Corresponding Efforts in China. Many observations in recent 100 years show that the earthâs climate is now. experiencing significant change characterized by global warming. And the trend of. climate change in China is generally consistent with that of global climate change.
Primase synthesizes the RNA primer that is used to start an Okazaki fragment on the lagging strand. DNA polymerase III continues to add nucleotides to the leading strand right at the replication fork. DNA polymerase I (not at the replication fork) replaces the RNA primers with DNA nucleotides. DNA ligase, also not at the replication fork fuses the new nucleotides produced by polymerase I with the adjacent strand. Replication continues until there are two completely seperate DNA strands that are identical.
Explain elongation stage of replication â you answer should include a discussion of leading strand, lagging strand, Okazaki pieces and RNA primer. Primase adds primer near inside of fork, DNA polymerase III adds nucleotides 5â-3â moving away from fork. After catching up to previous primer, DNA polymerase III must detach and move further into the expanding fork, after primase has added another primer deeper inside the fork.
