In these structures, supercoiling takes place due to the abnormal shape of the structure. A type of these structures is an episome which can become part of the normal DNA and remain there for long periods of time. A common property contained on these structures is a resistance to antibiotics, or the ability to utilize lactose for a food source. They are often used as vectors in cloning or putting 
In these structures, supercoiling takes place due to the abnormal shape of the structure. A type of these structures is an episome which can become part of the normal DNA and remain there for long periods of time. A common property contained on these structures is a resistance to antibiotics, or the ability to utilize lactose for a food source. They are often used as vectors in cloning or putting together recombinant DNA, due to their ability to replicate independently of the rest of the cell's DNA. FTP, name these small, circular pieces of DNA found in bacteria.          |
