Genome: Chromosome 1 - Life

In this chapter, life began with a single word: DNA. Life consists of two different skills, the ability to replicate and the ability to create order. The key to both of these is information. Information is the instructions for building and maintaining the equipment that creates order. The author relates genes to coded recipes, with its four repeated letters A, T, C, and G. A gene has 120 different letters that are constantly being copied into a short filament of RNA, the copy being called 5SRNA. The genes are able to replicate because of proteins. The author mentions how RNA may have came before proteins because RNA is a chemical substance that links DNA and proteins together; therefore, RNA must have come before. Ultimately, genes are the same everywhere, in all organisms and life. Their genetic code are the same and wherever we go and whatever organism we see, they will have the same codes and languages.
