Question

Briefly explain the relevance of DNA in advancing the study of biotechnology

Answer 1

Biotechnology is a branch of genetic engineering because the genes of an organism are changed during the process and the DNA of the organism is recombined. Recombinant DNA and biotechnology can be used to form proteins not normally produced in a cell.Genetic engineering, also called genetic modification, is the direct manipulation of an organisms genome using biotechnology. As well as inserting genes, the process can also be used to remove genes. The new DNA can be inserted randomly, or targeted to a specific part of the genome.Biotechnology has helped improve food quality, quantity and processing. It also has applications in manufacturing, where simple cells and proteins can be manipulated to produce chemicals.Biotechnology is the use of an organism, or a component of an organism or other biological system, to make a product or process. Many forms of modern biotechnology depends on DNA technology. DNA technology is the sequencing, analysis, and cutting-and-pasting of DNA.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.Biotechnology is the use of an organism, or a component of an organism or other biological system, to make a product or process.Biotechnology has applications in four major industrial areas, including health care (medical), crop production and agriculture, non-food (industrial) uses of crops and other products (e.g. biodegradable plastics, vegetable oil, biofuels), and environmental uses.

Examples of DNA technologies

• DNA cloning. In DNA cloning, researchers as clone make many copies of a DNA fragment of interest, such as a gene.
• Polymerase chain reaction (PCR).
• Gel electrophoresis. .
• DNA sequencing.
