WebAddition of an enzyme called DNA ligase, which takes part in DNA replication in cells, permanently joins the DNA fragments when the sticky ends come together. In this way, any DNA fragment can be spliced between the two ends of a plasmid DNA that has been cut with the same restriction enzyme (Figure 10.6). WebA DNA ladder—DNA that has been digested, producing fragments with known base pair sizes—should be run next to unknown DNA samples so that the sizes of the unknown samples can be determined. After creating smaller fragments of DNA from the source DNA, the length and purity of those DNA molecules can be determined using gel …

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. WebSizes of DNA fragments within a sample can be estimated by comparison to fragments of known size in a DNA ladder also run on the same gel.
