DNA polymerase of chicken embryo: purification and properties
Abstract:
The almost complete purification of the previously reported DNA polymerase of chicken embryo is described; in the final isolation step the enrichment of the enzyme, which comprises about 0.01% of the protein extractable from 10-day-old embryos, is more than 9000-fold. The enzyme is a basic protein (pI = 9.15), of molecular weight about 27,000. It exhibits no nuclease activity, requires Mn(2+) ion for activity, and may contain Zn. It is very sensitive to oxidation.

01:24DNA Isolation
DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...
01:31Proofreading
Synthesis of new DNA molecules is carried out by the enzyme DNA polymerase, which adds nucleotides on the daughter strand complementary to the template DNA strand. DNA polymerase has a higher affinity to add the correct base and ensures fidelity during DNA replication. Furthermore, it exhibits proofreading activity during replication, using an exonuclease domain that cuts off incorrect nucleotides from the nascent DNA strand.
