Chromosomes with equal arms are called:
Several chromosome regions have been defined by convenience in order to talk about gene loci. Most important is the distinction between chromosome region p and chromosome region q. The p region is represented in the shorter arm of the chromosome (p is for petit, French for small) while the q region is in the larger arm (chosen as next letter in alphabet after p). These are virtual regions that e… WebThe five human acrocentric chromosomes are numbered 13, 14, 15, 21, and 22. They all have a cytogenetically similar short arm that is extremely gene-poor. Their main contribution for the cell is that the acrocentric short arms are carriers of the nucleolus organizing regions (NOR) in subbands p12.
