SUMMARY
The discussion centers on calculating the number of guanines in a double-stranded DNA segment with 23 purines and 15 thymines. Given that purines consist of adenine and guanine, and that adenine pairs with thymine, the calculation confirms that there are 15 adenines. Consequently, subtracting the 15 adenines from the total purines results in 8 guanines, which is the correct answer.
