To determine the amount of cytosine in the DNA, we need to recall the base pairing rules of DNA. In double-stranded DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This means that the amount of thymine will always be equal to the amount of adenine, and the amount of cytosine will always be equal to the amount of guanine.
If there are 32 thymine bases in the DNA, then there are also 32 adenine bases due to the base pairing rule. The total number of bases will be made up of adenine, thymine, cytosine, and guanine. Since the question provides no information about the total amount of DNA, we can’t directly calculate the cytosine content from this information alone.
However, it is important to note that if the DNA molecule were to follow typical ratios that many organisms display, you might see some general proportions. But based solely on the information given (32 thymine), it is impossible to determine the amount of cytosine without knowing the total compositions of the other bases (cytosine and guanine).
Therefore, the answer is: e) it is impossible to tell.
