Answer:
You are Erwin Chargaff, an Austrian-American biochemist who made significant contributions to the understanding of DNA. Chargaff's rules, which he discovered through careful quantitative analysis of DNA composition, stated that the amounts of adenine (A) and thymine (T), as well as the amounts of cytosine (C) and guanine (G), in DNA are always approximately equal to each other. This finding was crucial in providing key insights that contributed to the development of the double helix model of DNA proposed by James Watson and Francis Crick. Chargaff's work laid the groundwork for the understanding of the base-pairing principles in DNA and was instrumental in shaping our understanding of genetics and molecular biology.
