WebHere the DNA to be copied enters the complex from the left. One new strand is leaving at the top of frame and the other new strand is leaving at bottom. The first step in DNA replication is the separation of the two strands by an enzyme called helicase. This spins the incoming DNA to unravel it: at ten thousand RPM in the case of bacterial systems. Web2 days ago · Ein Locus bezieht sich auf die physische Position eines Gens auf einem Chromosom. Homologe Chromosomen sind Chromosomenpaare von ungefähr gleicher Länge, Zentromerposition und Färbemuster für Gene mit denselben entsprechenden Loci.
