WebThe process is quite rapid and occurs with few errors. DNA replication uses a large number of proteins and enzymes ( Table 11.1 ). One of the key players is the enzyme DNA polymerase, also known as DNA pol. In bacteria, three main types of DNA polymerases are known: DNA pol I, DNA pol II, and DNA pol III. WebAsymmetry in the synthesis of leading and lagging strands. S phase ( Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G 1 phase and G 2 phase.

WebSection Summary. DNA replicates by a semi-conservative method in which each of the two parental DNA strands act as a template for new DNA to be synthesized. After replication, each DNA has one parental or “old” strand, and one daughter or “new” strand. Errors made during replication are typically repaired. pontotoc county mississippi property tax mapsWebOnce replication has been initiated; the replication forks progress along the DNA and participate in the synthesis of new strand. At the chemical level, the template dependent synthesis of DNA is very similar to the template-dependent synthesis of RNA that occurs during transcription, but the two processes are quite different. 1. pontotoc county ms deedspontotoc county ms property search
