If you read the newspaper or watch the news on TV, you have heard a lot about cloning. Do you know exactly what a clone is? According to the dictionary, a clone is a group of genetically identical cells that are descended from a common ancestor, such as a clone of bacterial cells grown from one bacterial cell in a laboratory. A clone could also be an organism that grew from a single parent by asexual reproduction. For example, an organism called a Hydra reproduces asexually by growing buds from its body. When the buds mature and drop off, they are new organisms that are genetically identical to the parent, and thus they are clones of the single parent hydra. A clone could also be a replica of a DNA sequence that is produced through genetic engineering.
