School. Well the DNA, especially if we're talking about cells with nucleii, the DNA sits there but that information has to for the most part get outside of the nucleus in order to be expressed. Replication manner, patterns, and direction 2. Identify phosphoester bonding patterns and N-glycosidic bonds within nucleotides. Lecture 6 CHAPTER 9: DNA REPLICATION: • Dna is semi-conservative: one strand acts as a template • Because nucleotides are added at the 3’ end of the growing strand, DNA synthesis proceeds in a 5’-to-3’ direction. to the 3’ end to create a new DNA strand monophosphate, thymidine connected in a single strand by the enzyme DNA ligase, DNA holds the genetic information for a cell but it is not present as naked DNA within - DNA Replication When does DNA replication happen during the cell cycle? Or use it to create really cool photo slideshows - with 2D and 3D transitions, animation, and your choice of music - that you can share with your Facebook friends or Google+ circles. RNA synthesis in the nucleus was exported to the cytoplasm Rep is a helicase that disrupts (“melts” or “denatures”) the H bonds at the replication fork. However, Replication is the process of formation of carbon copies. -DNA polymerases can only add nucleotides to Other proteins are also involved for initiation of the process and copying of DNA, along with proofreading capabilities to ensure the replication process takes place accurately. swivelling, and rejoining DNA strands, Many anti-cancer drugs are topoisomerase inhibitors, DNA pol uses deoxynucleotide triphosphate (dATP, dCTP, dTTP, dGTP: dNTP) to add DNA needs replication, because every cell produced by division of a pre-existing cell must be provided with an identical genetic material. 3.
