As of July 2014, the longest drop is at Zumanjaro: Drop of Doom at Six Flags Great Adventure, at 415 feet (126 m). A drop tower type of ride is distinct from an observation tower ride; the latter acts more like a traditional elevator, gently lifting riders up to its maximum height before lowering them gently as well.
The autosomes contain the rest of the genetic hereditary information. All act in the same way during cell division. Human cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell. In addition to these, human cells have many hundreds of copies of the mitochondrial genome.
Humans have a total of 46 chromosomes in each body cell; 44 of these are autosomes. You get one set of 22 autosomes from your mom and another set of 22 from your dad. It is often easier to think about our autosomes in pairs because even though we have 44 autosomes, we actually only have 22 types. We have two copies of each type of autosome, one from each parent. Two chromosomes of the same type, called homologous chromosomes, are the same size and shape and have the same genes. Our paired autosomes are numbered 1 through 22.
