How Do You Clone a Gene?
... Proteins are gene products and are important molecules in cells. Proteins do all the work that cells need to have done, such as carrying oxygen to cells, metabolism, and reproduction. Proteins also can be structural, such as the parts of cells and body structures. Proteins have specific shapes called ...

... In order to study a DNA fragment (e.g., a gene), it needs to be amplified and eventually purified. These tasks are accomplished by cloning the DNA into a vector. A vector is generally a small, circular DNA molecule that replicates inside a bacterium such as Escherichia coli (can be a virus). ...
