Geocache Description:

I thought I would share my science geek-ness with you in this geocaching series. I am a Cytogenetic Technologist. Cytogenetics is the study of chromosomes. I diagnose genetic disorders. All 24 caches in this series will be found in a 15ml centrifuge tube. I spin chromosomes in these at work every day!

Mrs. Rex

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 22, one copy inherited from each parent, form one of the pairs. Chromosome 22 is the second smallest human chromosome, spanning about 50 million base pairs and representing between 1.5 percent and 2 percent of the total DNA in cells. In 1999, researchers working on the Human Genome Project announced they had determined the sequence of base pairs that make up this chromosome. Chromosome 22 was the first human chromosome to be fully sequenced. Chromosome 22 likely contains between 500 and 800 genes. Changes in chromosome 22 are associated with chronic myeloid leukemia, Phelan-McDermid syndrome, DiGeorge syndrome, Emanuel syndrome, Opitz G/BBB syndrome, and Cat-eye syndrome.
