Ring Chromosomes

Ringe Kromosomer dannes når de to endene av et kromosom blir sammenføyd eller "smeltet sammen". Dette fører til at kromosomet er en sirkulær struktur (en ring) i stedet for en lang strenglignende struktur.

A ring can form in this way and not have any deleted (missing) chromosomal material. All of the DNA og genes are there, they are just arranged or packaged in a different structure. A ring chromosome can also be formed when there is a “break” on one or both ends of the Kromosomer, and then the ends of the chromosome become joined or “fused.” In this kind of ring, some chromosomal material is deleted or missing.
