HAPPY NEW YEAR, EVERYONE! WELCOME TO 2011! Now, let's all take a moment of silence in memory of 2010. Okay, so last year's gone. Last year, we had some good times. We went to Rock Eagle, we made it through Alice in Wonderland, a lot of new movies came out, including Harry Potter 7 part 1, The Lost Hero came out, and we went to the shuttle launch (in a manner of speaking). All great memories. All gone. But think of what we're going to do this year! We're going to go through another play, Robin Hood! The Son of Neptune will come out, the second Kane Chronicles Book is coming out, Harry Potter 7 part 2 is coming out...what more could we ask for (rhetorical question). Let's try to enjoy the New Year! (Peach drop---->)
Now, I know what you're probably thinking: "What the heck?". Well, if you'd just be patient, maybe I'd actually tell you. Okay? Ready to listen? Great. Today, we're learning about DNA. But we also have a guest: RNA. See, RNA is a great friend of DNA, and DNA kindly asked RNA to come to here. Now that you know the story, let's get started!
So, this song tells you all you need you know! Peace! HA! Yeah, right, like I'm going to do that. I'd get in trouble. Anyway, yes, it tells you the basic stuff. But you need to know more! You know that DNA is what makes you, you, and me, me.
Double Helix: DNA
Okay, so DNA stands for deoxyribonucleic acid. You can think of DNA as a computer program for your body. Everyone has different DNA, except for identical twins. Identical twins are like clones of one another(I'll get to that later) because they have the exact same DNA. Almost every cell in your body has a complete set of DNA. DNA is in the center of your cell, inside the nucleus. The shape is called a double helix, kind of like a twisting ladder. They come in long strands called chromosomes.
Normally, there are only four types of helix's: cytosine, guanine, adenine, and thymine. A DNA chain is so long, base pairs can arrange themselves in millions of different sequences. For example, adenine pairs up with thymine, and cytosine pairs up with guanine: ACGT or TGAC.
Helix
Each section of a DNA 'codes' for a different trait. Whether it's your hair color, your eye color, the size of your ears, how tall you'll be, or even if you'll end up with certain diseases. Each one is called a gene, which your parents pass their genes down to you.
RNA
Scientists research DNA for lots of different reasons. To name one: cloning. Identical twins are basically like twins because they're born with the same DNA. That's natural cloning. Artificial cloning is something completely different. The idea behind it is basically to copy the DNA of one animal and 'grow' a new one with the same DNA.
Okay, let's move on to RNA. RNA stands for ribonucleic acid. It carries out the orders of the DNA to the rest of the cell. That's not its only job, though. RNA is responsible for the making of ribosomes, the structures used to assemble protein strings, carrying amino acids in and out of their ‘storage’ in the cytoplasm, and carrying a copy of the genetic information located in the DNA to ribosomes for protein creation.
So, that's DNA and RNA. It's pretty simple stuff once you get to know it, and it's pretty much what helps us survive. Glad I could give you some information. Oh, and if any of you guys has seen a blue and white flash drive, please return it to me. Anyway, if you want to learn more, go to SuperSara's and youngro-jalenguy's blogs. Until next time!
Phew. So...bacteria. Yes, yes, I know what you're probably thinking: 'Ew, bacteria. Why would I want to learn about germs?' Well, the question is why wouldn't you want to learn about germs? Because, first of all, most bacteria is good, believe it or not. And even if they weren't, you'd want to know about them to prevent them, right? Right. Glad that's settled. Now, sit back, listen, and enjoy learning about BACTERIA!
So, the video tells you the basic stuff-- how germs can spread, why you should wash your hands before you eat, and never eat anything anyone else has touched, no matter how tempting it might be. But even though they looked like they could harm the woman, there's a chance that it won't make her sick. I mean, it probably will considering the man sneezed them out. But, like I said before, most bacteria are harmless. Some of them even help you.
First of all, bacteria are single celled organisms. They do not have a nucleus, but they do have a nucleoid. Some bacteria break down certain types of food to help us digest it. Some make nutrients that our bodies need. Some can even destroy some types of microorganisms that can make us sick. Less than one percent of bacteria actually harm us.
FUN FACT: Nine out of every ten of the cells in your body are bacterial cells, which means that most of your cells aren't your own.
Okay, now is time for my actual assignment: describe six parts of a typical bacterial cell and give their functions. That other stuff was just stuff you needed to know. Now, please try to enjoy yourselves, okay?
Good. Now, a bacterial cell is pretty simple. Here-
Nucleoid: The DNA in the bacterial cell is usually confined in the nucleoid. It isn't bound by a membrane, but it is still visibly distinct.
Ribosomes: Ribosomes make protein for the bacterial cell. A good way to remember this is to think of ribs. The word 'ribs' is in the word 'ribosome', is it not. And we all know that ribs give protein, so really, thay fit together.
Cell Wall: It maintains the shape of a bacterial cell.
Plasma Membrane: Responsible for the transport of ions, nutrients, and waste across the membrane.
Capsule: Protects the bacterial cell.
Flagella: It helps the bacterial cell move. Bacterial cells without flagella cannot move. It almost acts a 'motor'.
Pilus: Tiny and hairlike, pilus is made of proyein and allow bacteria to attach to other cells.
That's it for today. Hope you enjoyed, and, as always, if you want to know more, where do you go? That's right. To youro-jalen guy's blog and to SuperSara's blog. I'm 98% positive they have awesome information(never be completley positive). Peace, my home dawgs. ANOTHER FUN FACT: Did you know that there's more bacteria on you than there are people in the world?
