Background on Genomic DNA Isolation and Purification Generally‚ all methods involve the disruption and lysis of cells. This is followed sometimes by the removal of RNA (by RNAses‚ salt or other methods). Choosing which method to use will depend on many selection factors including: DNA is isolated from proteins by several methods including digestion of proteins by the enzyme proteinase K. Proteins are removed subsequently by salting-out‚ organic extraction‚ or binding of the DNA to a solid-phase

DNA replication mechanism is an integral and the most important part of cell division. It is a complicated mechanism that requires a lot of steps and different enzymes. Many scientists were trying to understand the mechanism of DNA replication and its role in the transfer of the hereditary information to the offsprings. DNA replication begins with a single origin of replication that starts off the process by creating a replication bubble. In many eukaryotic cells‚ the DNA strand will have more than

When Watson and Crick discovered the structure of DNA they wanted to use the information to help them identify how DNA is replicated. Three different theories of replication were proposed by Watson and Crick. The semi-conservative model‚ where the DNA strand splits into two halves‚ which will then create a new DNA strand consisting of the old original half and a new half. The conservative model where the whole of the original DNA strand acts as a template and is replicated to make a completely new
