Protein<\/span>, Genetic code<\/span>, DNA<\/span>, Gene<\/span>…<\/h2>\n

A human being is made out of 100’000 billion cells<\/span>… Each one has a nucleus, in which there are 23 pairs of chromosomes<\/span>; one of the chromosomes<\/span> comes from our mother, and the other from our father. A chromosome<\/span> is made out of a long twisted thread of DNA<\/span> (the double helix). DNA<\/span> is a succession of 4 different nucleotides<\/span>, known as A, T, G and C. There are 3 billion nucleotides<\/span> spread over 23 chromosomes<\/span>! This is what is called our genome<\/span>, i.e. our biological identity and the genetic heritage we pass onto our children.<\/p>\n

Much like a recipe book, each chromosome<\/span> contains a certain number of recipes, known as \u2018genes<\/span>\u2019. Over 20\u2019000 genes<\/span> are recipes for proteins<\/span>. When a cell<\/span> needs proteins<\/span>, appropriate genes<\/span> are \u2018copied\u2019, and the copies (called messenger RNAs<\/span>) are transferred to the ribosomes<\/span>, where the proteins<\/span> are made. It is thanks to our proteins<\/span> that we are able to breathe, to walk and to sense things. Without proteins<\/span>, there is no life.<\/p>\n
