Defining Creative Writing. You might have heard it called different things. Traditionally referred to as literature, creative writing is an art of sorts - the art of making things up. It's writing done in a way that is not academic or technical but still attracts an audience. Though the definition is rather loose, creative writing can for the most part be considered any writing that is original and self-expressive.
The term âchiasma,â 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.
Bivalent refers to the two homologous chromosomes (4 chromatids); chiasma refers to the actual break of the phosphodiester bond during crossing over. The larger the number of map units between the genes, the more crossing over occurs.hiasma frequency was scored at the later diplotene-diakinesis stages of meiosis. These results suggest that X-rays induce DNA damages, likely including double-strand breaks, and these damages are repaired by a crossover pathway leading to chiasma formation (see Chromosomal crossover).
