Organisms are finely tuned systems being resilient to perturbations but that have to keep some constants. As an example, inside the genome, the ratio between various gene services and products should be tightly constrained to make sure stoichiometric construction of protein buildings and stuff like that. Development has honed phrase amounts so when long as you have the same range chromosomes per cellular, the general transcription amounts of these genes are held constant (Fig 1).
Managing gene transcription through the intercourse chromosomes requires many distinct mechanisms. Image Credit: Image by Dr. Marian L. Miller.
Exactly what occurs in the event that ratio of chromosomes differs between people?Continue reading
