What is meant by recombinant DNA technology?

Recombinant DNA technology: A series of procedures that are used to join together (recombine) DNA segments. A recombinant DNA molecule is constructed from segments of two or more different DNA molecules.

What is recombinant DNA examples?

Through recombinant DNA techniques, bacteria have been created that are capable of synthesizing human insulin, human growth hormone, alpha interferon, hepatitis B vaccine, and other medically useful substances.

What is recombinant DNA and why is it used?

Recombinant DNA is used to identify, map and sequence genes, and to determine their function. rDNA probes are employed in analyzing gene expression within individual cells, and throughout the tissues of whole organisms.

What is the process of recombinant DNA technology?

Recombinant DNA (or rDNA ) is made by combining DNA from two or more sources. DNA fragments are cut out of their normal position in the chromosome using restriction enzymes (also called restriction endonucleases) and then inserted into other chromosomes or DNA molecules using enzymes called ligases.

Is recombinant DNA safe?

The first, and best known technique, is recombinant DNA (rDNA). It has been the subject of intense research and development during the past ten years and has been shown to be safe when used in the laboratory. The first commercial applications have been approved (e.g. human insulin, phenylalanine, human growth hormone).

Why Recombinant DNA technology is important?

The technology is important because it enables the creation of multiple copies of genes and the insertion of foreign genes into other organisms to give them new traits, such as antibiotic resistance or a new colour.

What is an example of DNA technology?

Common forms of DNA technology include DNA sequencing, polymerase chain reaction, DNA cloning, and gel electrophoresis.

What are the applications of recombinant DNA technology?

Recombinant DNA technology is widely used in Agriculture to produce genetically-modified organisms such as Flavr Savr tomatoes, golden rice rich in proteins, Bt-cotton to protect the plant against ball worms and lot more. In the field of medicines, Recombinant DNA technology is used for the production of Insulin.

Is recombinant DNA the same as genetic engineering?

Genetic engineering, also called recombinant DNA technology, involves the group of techniques used to cut up and join together genetic material, especially DNA from different biological species, and to introduce the resulting hybrid DNA into an organism in order to form new combinations of heritable genetic material.

How is recombinant DNA used in medicine?

There are many applications for recombinant DNA technology. Cloned complementary DNA has been used to produce various human proteins in microorganisms. Insulin and growth hormone have been extensively and successfully tested in humans and insulin has been licensed for sale.
