The table shows data Chargaff collected on DNA nitrogenous bases in five organisms.

null

1

Which statement did Chargaff conclude based on these data? Note that a letter in brackets, such as [A] or [C], refers to the concentration of one of the nitrogenous bases.

in DNA molecules, [A] = [T], and [C ] = [G]

in single-stranded DNA molecules, [A] = [T] = [C ] = [G]

in DNA molecules [A] = [G], and [C ] = [T]

in DNA molecules, [T] > [A] > [G] > [C]

Three babies were born on the same morning in the same hospital. When the babies were bathed, the identification bracelets slipped off and the nurses thought a mix-up may have occurred. The screen displays the DNA profiles of the babies and their parents. Use the DNA profiles to identify the parents of each baby.
