CHAPTER 4: DNA, CHROMOSOMES, AND GENOMES © Garland Science 2015 1. In a double-stranded DNA molecule, one of the chains has the sequence CCCATTCTA when read from the 5′ to the 3′ end. Indicate true (T) and false (F) statements below regarding this chain. Your answer would be a four-letter string composed of letters T and F only, e.g. TTFT. ( ) The other chain is heavier, i.e. it has a greater mass. ( ) There are no C residues in the other chain. ( ) The 5′-terminal residue of the other chain is G. ( ) The other chain is pyrimidine-rich. 2. Indicate which numbered feature (1 to 5) in the schematic drawing below of the DNA double helix corresponds to each of the following. Your answer would be a five-digit number composed of digits 1 to 5 only, e.g. 52431. ( ) Hydrogen-bonding ( ) Covalent linkage ( ) Phosphate group ( ) Nitrogen-containing base ( ) Deoxyribose sugar 1 2 5 3 4
