Recombinant protein

Proteins are a group of organic molecule combinations. Proteins are the most important of all the materials that compose all living organisms. Proteins are in each living cell of all organisms without exceptions and in the cells, the proteins are abundant in variety or types. All the characteristics of the organisms are determined by protein activity (such as eye color, immune system operation..)

Protein was known to science before the DNA and for long time was assumed that they are the genetic code carrier.
Protein is a huge molecule, the building blocks of protein are the amino acid, and a standard protein molecule is made out of many thousand of amino acids. The protein poses a complex 3-D shape, this shape determines many of the protein functions in the living body.

Creation of proteins
The proteins are created in the cells by the ribosome by a process called “Translation” in which a mRNA molecule (that was transcript from the DNA inside the nucleus) comes out of the nucleus to the Cytoplasm, this mRNA molecule carry the genetic code of the DNA and proteins are translated in the cytoplasm. In this process is involved another protein molecule called Ribosome.
Recombinant protein Types
Recombinant protein is a protein that it’s code was carried by a recombinant DNA.
The term recombinant DNA means that two segments of DNA in a plasmid. Plasmids are usually occurring in bacteria.
When a recombinant DNA is inserted to a bacteria, this bacteria will produce protein based on this recombinant DNA. This protein is called recombinant protein.
The use of bacteria in order to produce recombinant protein has grown in the recent years. Using recombinant DNA and inserting it to a plasmid of rapidly reproducing bacteria enables the manufacture of recombinant protein. These recombinant proteins can be variety of types, the can be Antibodies, antigens, hormones and enzymes.
