Is there always going to be an equal number of guanine and cytosine nucleotides in a molecules Why?

Answer 1

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.

Answer 2

If the DNA is double stranded then the short answer is yes because guanine always pairs with cytosine.
If the DNA were single stranded then there could be unequal amounts.

Answer 3

In DNA and RNA molecules the number of cytosine and guanine do not alter. Therefore, their number remains equal in their respective nucleotides.

Answer 4

SInce these always pair up, there has to be an equal number of molecules.

Answer 5

Yes, but only in DNA and not RNA. The reason is that these two always pair up.

Answer 6

yes
