centromérával
Centromérával is a term used in genetics to refer to the centromere of a chromosome. The centromere is a specialized region on a chromosome that plays a critical role during cell division. It is the constricted point where the two sister chromatids of a replicated chromosome are held together. During mitosis and meiosis, the spindle fibers attach to the centromere, specifically to a protein structure called the kinetochore that assembles on the centromere. This attachment allows for the accurate segregation of chromosomes to daughter cells.
The centromere is typically located in a specific position on each chromosome, which is used to classify
