If a dna strand has 19% cytosine before replication, what persentage of adenine will each new strand have after replication? show your work!

Since cytosine bonds with guanine, that means that they will each make up 19%, for a total of 38%. That means that there is 62% left for adenine and thymine, or uracil, each containing 31%. After replication, each compound percentage from the original DNA strand get halved, making the new percentage of adenine be 15.5%. I hoped this helped and I hope I SHOWED MY WORK!

it's c. (to reduce the greenhouse effect/carbon gasses)
