Since the eight reactions were run on fragments of random length, the eight plus and minus reactions collectively produced DNA fragments of all possible lengths.4 The fragments in these eight reactions were separated by size (using gel electrophoresis) and then imaged with autoradiography. Gels were dried and then placed against X-ray film, allowing the radioactive DNA fragments to expose the film and appear as dark bands, which a scientist could then painstakingly translate into the DNA sequence. In 1977, Sanger and colleagues sequenced the first full DNA genome using this method: a small bacterial virus with 5,386 nucleotides in its genome, called ɸX174 or “PhiX.”
A healthful plant-based diet is linked to an 11% lower risk of breast cancer and a 28% reduction in mortality for those already diagnosed. New research from 70,000+ participants shows that high intake of vitamins B2, C, and magnesium, combined with low sodium, significantly improves survival.
