Approximately 60 trillion cells that form a human body. And each cell has a human genome consisting of about 3 billion characters. The "Starfish Genom Map in the House" shows the genes name and location on the chime, which is about 1% of all the genes contained in the human genes (about 20,000) that are involved in various functions. It picks up some genes and introduces functions with an easy-to-understand illustration. The first edition (1st Edition) was released in 2016. This is the 4th version of the latest revision.
