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!

Humans normally have 46 chromosomes in each cell, divided into 23
pairs. Two copies of chromosome 2, one copy inherited from each
parent, form one of the pairs. Chromosome 2 is the second largest
human chromosome, spanning more than 243 million base pairs and
representing almost 8 percent of the total DNA in cells. Chromosome
2 likely contains between 1,300 and 1,400 genes. Changes in
chromosome 2 have been identified in several types of cancer.
