Is there always going to be an equal number of guanine and cytosine nucleotides in a molecules Why?
That depends on what the molecule is. In DNA, there will be the same concentration of each, because they are paired, and DNA is a double stranded molecule. Thus, for each cytosine, there will be a guanine, and vice versa. In RNA however, it is single stranded, so the two do not have to match exactly.
