Question

in a molecule of DNA there is 24 percent adenine, determine the remaining percentages of all other bases in this molecule of DNA?

Answer 1

Together, that is 40 percent of the total sample. You can subtract that 40 percent from 100 percent and determine 60 percent of the sample must be adenine and thyminetogether. Since those two bases always exist in equal concentrations, you know the DNA sample is 30 percent adenine.
