Don't look any closer the story gets more complicated if you do. The short story is that Chimera is a web browser. Some of the information in this writeup was taken from entries I wrote for the science dictionary at. A chimeraplast is a synthetic molecule made up of both RNA and DNA which is used in gene repair.Ĭhimeric mice and rats that contain select genes from other animal species (including humans) are widely used throughout biological and medical research and are particularly popular in the study of genetics, cancer, aging and developmental biology. On the molecular level, a chimera is also a recombinant DNA molecule created by joining DNA fragments from two or more different organisms. If the genetic alterations are significant, the organism may be sterile, but if it is fertile, it will be able to pass its novel genes on to its offspring. Such a chimera's fundamental genetic structure is different from that of any of its parent species. Retroviruses are often used to transform and transfer the DNA into the embryonic cells. In biology, biotechnology and genetic engineering, a chimera is a hybrid or composite organism created from two or more species that could not have naturally mated and reproduced.Ī chimeric organism may be made by introducing cells from the early-stage embryo of one species into another embryo, thus creating a composite animal (for example, a geep) that is not a true genetic hybrid.Ī truly genetically-engineered chimera is created by introducing recombinant DNA from one species into the genome of the cells of a blastula (early-stage embryo) of another species. This is different than a hybrid where two related species (such as the lion and tiger, or horse and donkey) mate to form an infertile offspring (such as the liger or tigron and mule). The most common example of this is the geep which was produced by injecting the goat inner cell mass into a sheep blastocyst. The chimera can also be formed by artifically implanting cells from one organism into the embryo of another. From this, the organism will have two sets of cells that have different DNA. Within animals, chimeras naturally exist when there is a mutation in one or more cells of a developing embryo (this is also true for plants and is often seen in tabacco). The essence of the chimera is that the organism consists of multiple tissues from different genetic backgrounds. Any being that has had a transplant from another is technically a chimera. The only way to make another tree (or rather branch of a tree) has been to form a chimera.Ĭhimeras have existed in animal biology for some time, though it wasn't until the advances in embryo development that the word became popularized. These fruits are formed from a mutation or selective breeding to not have any seeds and thus are infertile themselves. This is the process used to produce seedless fruits. The oldest form of creation of chimeras is from botany where a branch of one plant is grafted into the trunk of another. In today's world of science and biology, the chimera is an organism composed of tissues that are genetically different. These ranged from the sphinx (a human head on a lion's body) to that of mermaids, centaurs, and the Chimera itself. These often took the forms from mythology that was abundant with mixes of humans and animals in a body.
In the days of Gothic architecture, the chimera was a type of gargoyle that combined several different animals into one body. The lead melted from the firey breath and ran down the throat and hardened, killing the Chimera.
Instead, Bellerophon rode Pegasus (as directed by Polyidus, a soothsayer) and killed it with a lump of lead on the end of a spear stuck in its mouth after weakening it with an arrow. Instead, the king sent him off to kill the Chimera with the hope that Bellerophon would be killed instead. The siblings of the Chimera were Cerberus, the Hydra, and Orthrus.Īs part of a complicated betrayal and false accusation that is common in Greek mythology (the treacherous woman type), Bellerophon was sent the kingdom of Lycia to be killed by the king. The Chimera was the child of Typhon (a giant) and Echidna (half human female, half snake), and raised by Amisodarus. Some stories include the head of each, and the goat head could breath fire. Chimera from Latin chimaera, from the Greek chimaira meaning she-goat.įrom the days of Greek mythology, the chimera (pronounced "kih-MEE-ra") was a combination of several animals - it had the head of a lion, the body of a she- goat, and the tail of a serpent ( dragon).
