- Conversely, an achiral object, such as an atom, is symmetric; its mirror image is not truly opposite, but rather is indistinguishable from the original. In chemistry, chirality usually refers to molecules. Two mirror images of a chiral molecule are called enantiomers or optical isomers.Pairs of enantiomers are often designated as  right-  and left-handed. molecule is achiral (not chiral) when an improper rotation, that is a combination of a rotation and a reflection in a plane, perpendicular to the axis of rotation, results in the same molecule. For tetrahedral molecules, the molecule is chiral if all four substituents are different.

Definitions &Translations Chirality. A chiral molecule is a type of molecule that has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom. The term chiral in general is used to describe an object that is not superposable on its mirror image.

What is Chimerism? Chimerism is an rare disorder that mixes the chromosomal population in a single organism. In these cases, chimerism may manifest as the presence of two sets of DNA, or organs that do not match the DNA of the rest of the organism. In some cases, hermaphroditic characteristics, in other words, having both male and female sex organs, can be signs of chimerism.

In Genetics, what is a Chiasma? The term “chiasma,” which comes from the Greek, refers generally to an intersection or crossing. This term is also used in anatomy to refer to bundles of nerves at the point of intersection, like the optic chiasm, where the optic nerves cross each other.t the chiasma, the chromatids can exchange genetic information, resulting in new combinations of genetic material. When the chromatids separate and become sister chromosomes, they will contain a different mix of genetic material than their parent chromosomes.

X Inactivation The inactivation occurs early in development when the embryo consists of only a few cells. The inactivation is random – one X chromosome may be turned off in one cell and the other X chromosome inactivated in a neighboring cell.Once a chromosome is turned off it remains turned off in all descendent cells. With respect to their X chromosomes, female mammals are chimeras.A chimera is an organism composed of different genotypes. Some areas of their bodies have one X chromosome turned off and other areas have the other X chromosome inactivated.An example of X-linked chimeras that can be seen visually are female cats that are heterozygous at the orange coat color locus. Orange is a locus on the X chromosome.ith respect to their X chromosomes, female mammals are chimeras. A chimera is an organism composed of different genotypes.

Chiasmus Examples Chiasmus Examples. Chiasmus. Chiasmus is the term for a rhetorical device in which a sentence or phrase is followed by a sentence or phrase that reverses the structure and order of the first one. In chiasmus, the words do not have to be repeated-the second sentence does not just reverse the words of the first sentence. Different words can be used. The key is that the sentence is grammatically the same, just reversed. Writers and speakers use chiasmus for the effect.

Chimera (genetics) A chimeric mouse with its offspring. A chimera (also spelled chimaera) (from the creature Chimera in Greek mythology) is a single organism composed of genetically distinct cells. This can result in male and female organs, two blood types, or subtle variations in form.Animal chimeras are produced by the merger of multiple fertilized eggs.n animal chimera is a single organism that is composed of two or more different populations of genetically distinct cells that originated from different zygotes involved in sexual reproduction. If the different cells have emerged from the same zygote, the organism is called a mosaic.

What is a chiasm / chiastic structure in the Bible? Answer: A chiasm (also called a chiasmus) is a literary device in which a sequence of ideas is presented and then repeated in reverse order. The result is a mirror effect as the ideas are reflected back in a passage. Each idea is connected to its reflection by a repeated word, often in a related form.

Chirality In chemistry, chirality usually refers to molecules. Two mirror images of a chiral molecule are called enantiomers or optical isomers. Pairs of enantiomers are often designated as  right-  and left-handed. molecule can have multiple stereogenic centers without being chiral overall if there is a symmetry between the two (or more) stereocenters themselves. Such a molecule is called a meso compound. It is also possible for a molecule to be chiral without having actual point chirality.
