Molecular mechanism of DNA replication - Khan Academy

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. WebApr 8, 2016 · Bacteria reproduce by a process called binary fission. In binary fission (shown in Figure 2), the bacterium first duplicates its DNA, so it has two identical copies of genetic material. The cell then swells and elongates as it gets ready to split, with the copies of DNA moving to separate sides of the cell. A divider then forms in the middle of ...

WebDNA cloning is the process of making many copies of a specific piece of DNA, such as a gene. The copies are often made in bacteria. In a typical cloning experiment, researchers first insert a piece of DNA, such as a gene, into a circular piece of DNA called a plasmid.

WebKey points: In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells. Transposable elements are chunks of DNA that "jump" from one place to another. http://needtoknow.nas.edu/id/infection/microbe-types/bacteria/

WebKey points: DNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and …
