What is molecular cloning?

Molecular cloning refers to the replication and recombination of DNA molecules, which makes many identical copies of a piece of DNA, such as a gene of a genome, enabling the manipulation and study of genes. The workflow of cloning has four steps: 

1. DNA is isolated

2. Isolated DNA is inserted into a cloning vector

3. Vectors are propagated in a host

4. Hosts containing the DNA insert are selected

Cloning small fragments of a genome allows specific genes, their protein products, and non-coding regions to be studied in isolation.
