Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

I believe the correct answer would be metabolism. This comprises all of the reactions inside organisms that allows them to sustain life. There are two categories of such namely, anabolism and catabolism. Hope this answers the question.
Hello Wtfiswrongwitmeh, using radiocarbon dating, or carbon dating, you can determine the age
of an organic object from the relative proportions of the carbon
isotopes it contains. Therefore, if you take the fossils form the fossil
record and determine how old they are, you can see how/if they evolved
over time.
