Some people think that modifying human genes is dangerous or wrong. Production of human insulin is one the biggest contributions of genetic engineering. Like a recipe book it holds the instructions for making all the proteins in our bodies. Although each DNA molecule contains many of these building blocks, only four unique nucleotides are used to create the entire DNA sequence; these are written as A, G, C and T. Analogous to how the 26 letters of the alphabet can be arranged to create words with different meanings, these four nucleotides can be arranged in sequences to "spell" the genetic instructions to create all of the different proteins organisms need to live. Drawing on Smiths work, American molecular biologist Daniel Nathans helped advance the technique of DNA recombination in 197071 and demonstrated that type II enzymes could be useful in genetic studies. Units serve as guides to a particular content or subject area. DNA: Acronym for deoxyribonucleic acid, which is a molecule that contains an organism's complete genetic information. These foods are generally extracted from organisms that have had some changes in their DNA with the help of genetic engineering. The expression of a gene in an observable manner is called a phenotypic trait; one example is an organism's hair color. DNA molecules, single genes, and other types of genetic materials are responsible for the traits in everything from our food supply to our own bodies. things that look like this. Development of new antibiotics also needs this technology. Genes are tiny units that carry information about an organism. Products of genetic engineering are common nowadays in our daily life.
