WHAT IS THIS? Question: Does any one know what this is? DNA or deoxyribonucleic acid is a long molecule that encodes our genetic instructions. DNA has a distinctive double helix shape, like a twisted ladder. Two strands of DNA are twisted together into the double helix shape. The rungs on the DNA ladder are called base pairs.

THE DNA CODE G A C T C T G A DNA is made of four bases or DNA letters: A, C, G, T DNA bases always pair in the same way A always pairs with T C always pairs with G Because of this loyal pairing, if you know the letter on one side of the DNA you will always know what the other side will be. The sequence or order of the DNA letters provide instructions or code for the cell to make proteins. The building blocks of life.
