Recombinant dna

---

Originally from Santa Fe, New Mexico Dr. Villa Komaroff was a key member of the team that showed for the first time that bacteria could be induced to produce insulin. The research was a milestone in the development of the biotechnology industry. 

How did they make insulin from recombinant DNA?

A SIDE NOTE :: Polymerase chain reaction (PCR) is another method that can be used to replicate a specific DNA sequence and create rDNA, which is used to replicate DNA in a laboratory test tube learn more..

Recombinant DNA, which is often shortened to rDNA, is an artificially made DNA strand that is formed by the combination of two or more gene sequences. This new combination may or may not occur naturally, but is engineered specifically for a purpose to be used in one of the many applications of recombinant DNA. In most cases, rDNA is created in a laboratory setting using a process of molecular cloning. This method allows in vivo DNA replication, in the living cells of the subject.

A cloning vector is a DNA molecule that replicates inside a living cell and is used to form rDNA. The cloning vector is usually a small part of a DNA strand that holds the genetic information that is needed for the replication of cells.
