I'm studying for a huge air test and could REALLY use some help! whether I go onto the next grade or repeat a year depends on knowing everything so I'm kinda freaking out??? Like I haven't taken biology in over a year and I don't remember SQUAT. I can't check the answers, so I trust that the answer I get will be correct! Thank you so much to whoever sees this!

Answer 1

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.
