In a human genome project, scientist notices that one strand of the DNA molecule contains 20 thymine (T), 25 cytosines (C), 30 guanines (G) and 22 adenine (A) residues. How many of each of the bases are found in the complete double-stranded molecule?
Base pairs occur when nitrogenous bases make hydrogen bonds with each other. Each base has a specific paner: guanine with cytosine, adenine with thymine (in DNA) or adenine with uracil (in RNA). The hydrogen bonds are weak, allowing DNA to 'unzip Reference satyanarayana 4e
