DNA Sequencing

After missing a few days of class, my friend Caryn helped me catch on. When I came back, I did a DNA sequencing worksheet, kind of an old fashion way of finding out which one has a disease. I think Carol has it because her number is much lesser than Abby and Bob. As you can see from the graph I created from doing the lab. How to determine the numbers is by looking at their DNA structure. And seeing which strands of DNA is different compared to the others. 

DNA Lab

Our lab that we did today was getting DNA from wheat. The DNA as you can see is stringy and white and is in between the wheat and alcohol. By adding hot water first to the wheat started to thicken up the wheat. We think its because so the DNA can thicken. Then putting alcohol, it helped finish getting the DNA out from the wheat. It looked all stringy and kinda like webs. We got our stirring stick and fished out the DNA. On the stick, it looked all mushy and gross. Caryn and I touched it and it was a gooy. I really liked this lab and thought it was pretty cool.

DNA!!!! Dun Dun DUnnnnnnn

As of like, 5 mins ago, we took a picture of our DNA that we just made. The white strands is the phosphate, or sugar. The orange is the A, the green is the T, which only connect to each other. Then, the blue is the G, and yellow is C. Those only connect to each other. And by doing this, Caryn and I made DNA. We stuck it on other strands of DNA with our class and made one big strand.  Dun, dun, dunnnnn!!

Olga & Greg Pedigree

 This paper that I'm holding up is Olga's pedigree. What I mean by that is it's basically her family tree, but seeing if some diseases that she has in her family will get passed down the line. 

Greg's on the other hand, isn't as big as Olga's family tree, but it's the same prosses. 

Taste Buds.

I would say about a week ago, Mr. Ludwig gave us each a little strip of paper to see who can takes it and who couldn't. Surprisingly, only about two people in my class couldn't taste it. And that was derek and I think curtis. The rest of us could taste it. The strip to me tasted like bad garlic. It was nasty. How some people who can't taste it, don't have that particular gene in their tongue. The rest of us, of coarse does have that gene. Stay tuned for more info =]

Making a baby with Dillion

So Friday, we did a little project on making a baby by getting with a partner and looking at each others traits and seeing what our baby would look like. Dillion and I ended up flipping a coin and got a girl. How this is, is a man gives a X and a Y trait in the sperm. The egg of a women has a XX trait. As I said, we flipped a coin and got a girl. On a piece of paper, it asked questions like eye color, skin color and etc. And by flipping a coin, we determined how our daughter would look like. With a brown hair girl and a blonde hair guy, our daughter would have black hair, how, I have no idea. And with blue eyes and hazel eyes, she will have brown. It was kind of weird, but today, we got to draw on how she looked like. Dillion, now his drawing of her wasn't pretty. She looked like a monster. Mine on the other hand, was ok. Better than his. But it was a pretty fun experiment.

Babies and Cloning

Yesterday, we watched a small video about cloning. All they did was stick a tube like thing in the membrane and took the nucleolus and put it into another cell or egg. Thats how one cloning was in the video. There are reproductive cloning and therapeutic cloning.
Reproductive cloning is to try and generate an animal DNA into another animal's DNA who is somewhat similar. Kind of what the video was showing.
Therapeutic cloning, known as "embryo cloning", is not to create cloned human beings, but rather to harvest stem cells that can be used to study human development and to treat disease. To learn about more click here.
