 All right, I skipped the two middle ones, but I'm back to our chart for nucleic acids. Ooh, what? What? It's late. I will not get into a habit of recording these late. I'm not a huge fan of this late hour, but get all this prepped today. I wanted to get it done. Nucleic acids have a subunit that I want you to know, and it is the nucleotide. And I'm going to talk about nucleic acids, but nucleotides, all nucleotides have the same structure. They have a phosphate attached to a sugar, attached to a nitrogen base. That's it. That's a nucleotide. Now we have some flavors and we're going to start off loud and proud with different important nucleotides. ATP is a really important nucleotide. I think I have a picture of it in here for you. Let me see if I do indeed. I didn't put it in there. ATP is a really important nucleic acid that's made of, it's called adenosine triphosphate. So it has an adenine, a ribose, and three phosphate molecules. The ribose is the sugar. Ribose, RNA, ribonucleic acid. RNA is an example of a nucleic acid. DNA, deoxyribonucleic acid is an example of a nucleic acid. RNA and DNA are involved in building proteins. I already said that because I got so excited in the protein section. They literally provide the instructions for how to build the proteins that allow you to function. ATP, which is another super important nucleic acid, ATP provides energy to your giddy up. I can't remember if we talked about ATP yet. I kind of feel like we did somewhere, but that could be just because I'm trying to get us ahead to the section where we get to talk about energy, which is after our first exam. We spend three entire lessons, three entire lectures on the structure and function of DNA, how DNA works, how mRNA works, why an mRNA vaccine could work well for us. There's tons of information coming around nucleic acid, so I don't feel so bad making this a very short piece. How long was this lecture? I don't know. I feel like this is probably one of the longest ones we'll have. I don't think that we'll all go this long. Good night, everybody. Sweet dreams!
