WebJul 5, 2024 · So without any reference; the gel run doesn’t make sense. The DNA ladder is simply a composition of standard-size fragments that runs according to their fragment size. It helps to determine the size of DNA fragments. Like the DNA ladder, RNA and protein ladder do exist and are used in various biological experiments. 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.
