cloud. âThe surface of the earth changes. Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, earthquakesâ and collisions by large meteorites with the earth.
DNA gyrase, often referred to simply as gyrase, is an enzyme that relieves strain while double-strand DNA is being unwound by helicase. It is also known as DNA topoisomerase II.This causes negative supercoiling of the DNA.his process occurs in prokaryotes (in particular, in bacteria), whose single circular DNA is cut by DNA gyrase and the two ends are then twisted around each other to form supercoils. Gyrase has been found in the apicoplast of the malarial parasite Plasmodium falciparum, a unicellular eukaryote.
DNA replication. 1. Helicase unzips the double helix 2. DNA polymerase uses one strand to copy the information to produce another complementary strand 3. DNA polymerase connects individual nucleotides to their corresponding bases to connect the DNA molecule 4. DNA polymerase proof-reads the DNA. î î î.
