Gene cloning occurs when a specific gene from a strand of DNA has been extracted and copied from an organism. Nearly any tissue source can be used for cloning, as long as there is not widespread degradation. DNA can also be extracted from RNA using a process called reverse transcription.Continue Reading
Genes are made from DNA and contain the basic building blocks of heredity. When a gene is cloned, an exact replica is produced. The process requires a variety of biotechnical techniques.
A basic explanation of the process of cloning a gene:
Dangers associated with cloning include a chance of developmental issues arising later in life, a low success rate, which necessitates time-consuming and cost-intensive repeat cloning attempts, gene abnormalities and differences in chromosome lengths and patterns. Cloning occurs in many living organisms; some cloned species develop normally while others show abnormalities at birth or later in life.Full Answer >
Gene splicing is a technique used in genetic engineering where the DNA of a living thing is edited, in some cases replacing existing genes with genes taken from another plant or animal. Enzymes are used to cut the DNA strand and remove a piece, which can then be replaced with new information. This can transfer characteristics from one species to another or give an organism entirely new characteristics.Full Answer >
The National Institutes of Health defines therapeutic cloning as cloning an embryo only for the purpose of producing embryonic stem cells with the same DNA as the donor cell. Therapeutic cloning aims to create stem cells for the express purpose of experiments so that researchers gain a better understanding of disease and work to develop effective treatments for diseases in humans.Full Answer >
There are three types of cloning that are mainly used: reproductive, therapeutic and DNA. Cloning is the process of producing a genetically identical organisms that exists in nature.Full Answer >
