Ah, life... a sunny day... a simple friend... ... and a complex biological story. Almost all of our cells - the muscle cells that let us smile, the brain cells that perceive the humour in things, the cells of our eyes that take it all in, contain a complete set of all our genes, the GENOME. If we could journey inside ourselves into a cell, we would see 23 pairs of chromosomes, packed into a nucleus. Each chromosome contains a long coil of DNA. If all the chromosomes were unwound, the DNA in just one of our cells would stretch 6 feet (2 metres) long! The DNA double helix contains four kinds of building blocks. An A always pairs with a T, a C with a G. DNA contains information to make every part of our bodies with its four-letter language. Each of our thousands of genes codes for a specific part. RNA polymerase copies the information in a gene into a messenger molecule, messenger RNA. The building blocks of messenger RNA and DNA are called bases. The bases on one strand of the DNA specify the order of bases on the new strand of messenger RNA. The DNA always stays inside the nucleus, but messenger RNA travels out into the cytoplasm. There, a protein making machine called a ribosome can read messenger RNA to make a particular protein. Every 3 bases of the messenger RNA molecule codes for an amino acid. Proteins are made of amino acids. tRNA molecules help translate the language of DNA and RNA into the language of proteins. tRNA molecules bring the right amino acids that the ribosome links together to make a protein. Proteins are the labourers... ... some form structures like tendons and hair, others perceive light, scents and flavours, control chemical reactions and carry messages between cells. To understand our molecular selves, scientists have read the 3 billion letters making up the DNA in the human genome. Different sets of genes, interacting with complex environmental factors, influence things like our looks, personalities and risks for diseases like cancer and heart disease. A growing understanding of our genes and all they do will help us understand the complexity and the wonder of life! A simple freindship, a sunny day, a life! The end
