I have an existing driveway that is eight years old. Its dimensions are 30-by-60 feet. I just have a binder coat on the driveway. I also have some low spots that are 1 to 2 inches where the concrete garage floor meets the driveway. The driveway is sealed every two years with Jet Black seal coat. The driveway is in good condition overall with some minor cracks.
Two scientists, James Watson and Francis Crick, worked out the structure of DNA. By using data from other scientists they were able to build a model of DNA. The data they used showed that bases occurred in pairs.
James Watson, Frances Crick and Rosalind Franklin played a significant role. Franklin used x-ray diffraction on DNA to find out more about its structure. Watson and Crick used Franklin's data, and other info, to build a model of the structure of DNA.NA (Deoxyribonucleic Acid) is the 'instruction manual' of how to build life. DNA defines everything, from microbes to plants to humans. DNA is what determines your appearence, such as facial features, hair colour and height.
