What is a ring chromosome

We have learnt that humans usually have 23 pairs of Chromosomes per cell, but what exactly is a ring chromosome?
Chromosomes usually have a top and a bottom, but in a ring chromosome for some reason a chromosome forms a circle.
One of the mysteries of ring Chromosomes is why the ends of the chromosome stick together and why the ring formation causes the problems that we see in individuals. We’ll be exploring this later in this series to see if we can UNRAVEL this mystery…

that ring Chromosomes occur in 1 in 30,000 to 60,000 live births, with chromosome 20 being one of the more commonly reported rings? So ring Chromosomes are actually not that RARE.
