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!

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
