Biotechnology is the use of living systems and organisms to create new technologies. On the simpler end of the spectrum, baking bread with yeast is an example of this interdisciplinary science. On the more complex side, genetic engineering, biochemistry, and molecular biology are pushing boundaries in an effort to treat illnesses, develop new biofuels, and grow plants more efficiently to feed more people. Use these resources to dig into biotechnology with your students. cells that make up every part of an organism; not a sperm or egg cell Text on this page is printable and can be used according to our Terms of Service . cell or group of cells that is genetically identical to its ancestor cell or group of cells. Heredity, or the passing of characteristics from one generation to the next, is a concept that humans have used for thousands of years as we’ve cultivated crops and selectively bred animals. But the first formal genetic study was undertaken by a monk named Gregor Mendel in the middle of the 19th Century. Mendel bred peas and noticed he could cross-pollinate them in certain ways to get green or yellow seeds. Today, the field of genetics is breaking new ground searching for new ways to treat disease or develop crops more resistant to insects or drought. Empower your students to learn about genetics with this collection of resources. Researchers can use clones in many ways. An embryo made by cloning can be turned into a stem cell factory. Stem cells are an early form of cells that can grow into many different types of cells and tissues. Scientists can turn them into nerve cells to fix a damaged spinal cord or insulin-making cells to treat diabetes. Two beagle puppies successfully cloned in Seoul, South Korea. These two dogs were cloned by a biopharmaceutical company that specializes in stem cell based therapeutics. Some clones already exist in nature. Single-celled organisms like bacteria make exact copies of themselves each time they reproduce. In humans, identical twins are similar to clones. They share almost the exact same genes. Identical twins are created when a fertilized egg splits in two. unborn animal in the early stages of development.

Genes, cells, tissues, and even whole animals can all be cloned. National Geographic Headquarters 1145 17th Street NW Washington, DC 20036 Animals are cloned in one of two ways. The first is called embryo twinning. Scientists first split an embryo in half. Those two halves are then placed in a mother’s uterus. Each part of the embryo develops into a unique animal, and the two animals share the same genes. The second method is called somatic cell nuclear transfer. Somatic cells are all the cells that make up an organism, but that are not sperm or egg cells. Sperm and egg cells contain only one set of chromosomes, and when they join during fertilization, the mother’s chromosomes merge with the father’s . Somatic cells, on the other hand, already contain two full sets of chromosomes. To make a clone, scientists transfer the DNA from an animal’s somatic cell into an egg cell that has had its nucleus and DNA removed. The egg develops into an embryo that contains the same genes as the cell donor. Then the embryo is implanted into an adult female’s uterus to grow. Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements. early cell that can develop into any type of cell or tissue in the body strand of DNA and associated proteins in the nucleus of cells that carries the organism's genetic information. The cloning of animals has been used in a number of different applications. Animals have been cloned to have gene mutations that help scientists study diseases that develop in the animals. Livestock like cows and pigs have been cloned to produce more milk or meat. Clones can even “resurrect” a beloved pet that has died. In 2001, a cat named CC was the first pet to be created through cloning. Cloning might one day bring back extinct species like the woolly mammoth or giant panda.

Scientists also make clones in the lab. They often clone genes in order to study and better understand them. To clone a gene , researchers take DNA from a living creature and insert it into a carrier like bacteria or yeast. Every time that carrier reproduces, a new copy of the gene is made. Heredity, or the passing of characteristics from one generation to the next, is a concept that humans have used for thousands of years as we’ve cultivated crops and selectively bred animals.

These two dogs were cloned by a biopharmaceutical company that specializes in stem cell based therapeutics. In 1996, Scottish scientists cloned the first animal, a sheep they named Dolly. She was cloned using an udder cell taken from an adult sheep. Since then, scientists have cloned cows, cats, deer, horses, and rabbits. They still have not cloned a human, though. In part, this is because it is difficult to produce a viable clone. In each attempt, there can be genetic mistakes that prevent the clone from surviving. It took scientists 276 attempts to get Dolly right.
