1. The problem statement, all variables and given/known data
If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?
2. Relevant equations
purines are adenine and guanine...adenine and thymine should be equal amounts. So, there are 15 adenines. Out of the 23 purines, there must be 8 guanines??
3. The attempt at a solution
8 guanines
