If a species has 35% adenine in its DNA, what is the percent of the other three bases?

Answer 1

Since adenine pairs with thymine in double-stranded DNA, we know that amount of A = amount of T. In this case, A=35%, so T=35%. The total will be 100% (for all 4 bases); the remaining 30% will be divided equally by guanine and cytocine, resulting in G=15% and C=15%.

G=15%, C=15%, T=35%, and A=35%

If a species has 35% adenine in its DNA, then the other three bases will account for the remaining 65%. Since DNA is double-stranded and adenine pairs with thymine, the percentage of thymine would also be 35%. Therefore, the combined percentage of guanine and cytosine would be 65%. If we assume an equal distribution of guanine and cytosine, each would account for half of the remaining 65%, which would be 32.5% each.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
