Study notes on Fidelity of Replication! Fidelity of replication means the faithful replication of DNA and the production of accurate daughter DNA using the parental DNA as a template. The accuracy of DNA replication is critical to cell reproduction. To produce a sequence of bases in the DNA of a daughter cell which is identical to that in the parent, [...]
The following points highlight the three main enzymes of DNA replications. The enzymes are: 1. Primase 2. DNA Polymerase 3. DNA Ligases. Enzyme # 1. Primase: A primase is an enzyme which makes the RNA primers required for initiation of Okazaki pieces on the lagging strand. Primase activity needs the formation of a complex of primase and at least six [...]
Explanations on Deoxyribose Nucleic Acid and Ribose Nucleic Acid. Deoxyribose Nucleic Acid (DNA): Watson and Crick (1953) have proposed a model for the structure of DNA molecule which is now usually accepted by all. According to this model called as Watson Crick Model, the DNA molecule is a double helix structure consisting of two long polynucleotide chains coiled round each [...]
