If a DNA strand has 35 cytosines how many adenine are there?

You must learn by reading and understanding what the concepts are that you have been asked to learn. You will not be allowed to have any learning aids while taking a test or quiz, so the best way to do this is to learn the material. You will be able answer many different questions that way.
The genetic information of a cell is stored in molecules of deoxyribonucleic acid (DNA).
DNA is a polymer of nucleotides . A DNA molecule consists of three parts—a nitrogen base, a five-carbon sugar called deoxyribose, and a phosphate group.
There are four DNA nucleotides, each with one of the four nitrogen bases (adenine, thymine, cytosine, and guanine). The first letter of each of these four bases is often used to symbolize the respective nucleotide (A for adenine nucleotide, for example).
DNA forms a two-stranded spiral, or double helix. Note that adenine always bonds with thymine and cytosine always bonds with guanine.
Since you have 35 C, you will have 35 G. Without knowing the number of thymine, the number of adenine is unknown .
That is all the information you can get from this. Just because there are 35 C and G, there doesn't have to be an equal number of A and T
