It has 46 chapters. Each chapter has many paragraphs.You have a friend who is also made of lego blocks. He was put together according to an instruction book that is nearly the same as yours, but not quite. It has 46 chapters like yours, but a few of the paragraphs are different to yours.

He was put together according to an instruction book that is nearly the same as yours, but not quite. It has 46 chapters like yours, but a few of the paragraphs are different to yours.Now imagine there are 8 billion people made of lego blocks, and nearly all of them have the same instruction book, with slight variations.This shared instruction book is the human genome. Other living species, such as animals, plants and bacteria have genomes too, but these are different to the human genome. For example, they usually have a different numb
