Okay, biology isn't exactly my strongest subject (it never has been), but I'm pretty sure the answer is nucleotides. DNA is made up of nucleotides. Each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. There are four different nitrogen bases: adenine (A), thymine (T), guanine (G), and cytosine (C). A always pairs with T, and G always pairs with C.
First of all, you spelled during wrong, but whatever, It still makes sense and i will still solve it. Your answer to this is: This is a short answer but still alliable. I think, and know at the same time, it is mitochondria.
Really hope helps!-aparri
