who knows anything about the double helix?

just internal organ systems of humans
we did digestive, respiratory, and circulatory systems

I love internal systems, it's so amazing how life works, with all the hormones and enzymes and stuff
it's so interesting to learn how your food goes down and how the different muscles and valves respond and how the body sends hormones to release the different enzymes.
Are you taking grade 11 biology?
Right here, science course only specialize into different branches like biology, chemistry and physics in grade 11 and 12. school only offers general science course in gr 9 and 10, and they are so easy, no details or anything until the last two years of high school

I was in 9th grade this year, most of the people in the class were in 10th. Were I am I have to take four science classes to graduate, physical science(physics, chemistry, or physical science), earth science(or enviromnental), biology, and one other. We have something called block schedualing which means we have 8 classes a year instead of 7, and means you don't learn as much in the class since it is shorter. Then, you can also take Advanced Placement classes which give you colledge credit. In the fall I get to take environmental science and chemisty. That will be cool!

wow you sure learn a lot of stuff in grade 9 (or 10) biology, I remember when I was in grade 9, all we studied for the biology part of the course were cells and reproduction (sexual and asexual), and in grade 10, we mainly learned biodiversity and ecology, and some physics, chemistry and meterology, we never got into any detailed stuff in gr 9 and 10

 

It's the only Bio class I have to take, it's good I learned stuff!

 

only bio class? well I am taking biology in grade 12, I heard it's mainly going to be about biochemistry - thus much harder

 

North Carolina education isn't that great. I got to read alot on my own to keep up with the rest of the world.

 

yep reading is very important, books are very important sources of knowledge enrichment
well Ontario education system is supposed to be the hardest in all of Canada, but I still need to read extra stuff to be able to get good performanaces in school

 

Your lucky. I would give anything to go to a challenging school were you actually have to think and you lean alot of stuff!

 

yeah thanks, not a lot of students seem to like it though, because it's pretty fast-paced and they can't keep up

for some reason, I always thought that U.S. education is more difficult than Canadian education, and the competition is more intense. I mean, you have to take the S.A.T.'s in the US to get into universities, but there is no such thing here in Canada. and there are many more prestigious universities in the U.S. too like Yale, Harvard, Stanford, Princeton...

 

The S.A.T.'s don't determine what college you can get in, or so I hear..

 

Well, I live in the south (I AM NOT A SOUTHERNER!), and there are a LOT of slow people. They want every one to be equal, so they spend a lot of time helping the kids who arn't very smart, and blow of the geniuses like me. (alright, I'm exagerating about the geniuses but...) I suppose competition wise it is intense. I don't know. I haven't gotten that far yet.

 

oh I see, there are lots of slow people here too, and the smart or more capable people are always encouraged to seek enrichment, and some of them in grade 12 have decided to write the SAT's and go to universities in the US, and I know one person who scored exceptionally well on it, and I think he got an early acceptance to Princeton

 

Here they pretend like we don't exist. It's amazing how much attention you get if you're labeled Academically Gifted, and all of a sudden you start failing all of your classes!

 

Wait does anyone know what Royolistic actually wanted to know about DNA???

 

haha good question, where the heck is he?

 

He didn't specify what we wanted to know. Not our problem. But we could start posting random facts about it again.

 

good idea

I'll start with the basics.

DNA - deoxyribonucleic acid - discovered by Francis Crick and James Watson - doubled stranded structure, also known as "double helix", made of sugar, phosphate, and nitrogenous groups. a nitrogenous group forms the "rung" of the double stranded structure, and sugar and phosphate form the backbone of the double helix

RNA - ribonucleic acid - singled stranded - produces proteins
