“If uncoiled, the DNA in all the cells in your body would stretch 10 billion miles, from here to Pluto and back.” Answer : DNA is like tiny coils of spaghetti, smaller that can be seen by the human eye, inside every cell in our body. These are the instructions for building the human body. There are approximately 10 trillion ... body, so when we put all the tiny DNA strands end to end they stretch really really far!...
Sections of DNA that code for proteins are called genes. The complete set of genetic information for an organism is called the genome. The latest estimate is that there are between 20,000 and 25,000 genes in the human genome.
Every day an adult body produces 300 billion new cells. Your body not only needs energy to keep your organs up and running but also to constantly repair and build new cells to form the building blocks of your body itself.
DNA is found inside every cell in our body (apart from red blood cells).
The four letters in the DNA alphabet - A, C, G and T - are used to carry the instructions for making all organisms. The sequence of these letters holds the code - just like the order of letters that makes words mean something. Each set of three letters corresponds to a single amino acid.
