Fabulous Bio93 Review Competition!

There's no worksheet to print for discussion on Friday. Instead, gather up your lecture notes from the past half of the course, and spend about an hour reading over all the lectures. We'll have an in-class competition of sample exam questions. Such a party!

Best review packet for Bio 93

Do you feel overwhelmed by the material you need to study for Bio93? Do you wish someone would tell you what's important from each lecture? Do you want to start studying now, but don't know what to do besides re-reading your notes? I've got the answer! A Bio93 Wiki!

No, sorry. I'm not going to write you up a big list of every important topic from each lecture. But I do think that creating a review sheet is a good study skill. So let's work together to make an online, editable review sheet. I have 90 students, and there are 29 lectures. So... why don't you work on making a review sheet for one lecture, and other students can make one for other lectures, and you can build a really big review sheet? Work on this as much as you like, and I will check the wiki regularly and make corrections and suggestions as you donate.

I've set up the wiki here:
I set up the lecture headings already. Anyone can edit the space, so give it a whirl and let's see if it is helpful to you all.

Quiz results

Hi all!
Most of you did very well on the online quiz. The question missed most often was the one about what TATA boxes and poly-A tails are made out of. Some of you were a bit floored by the pedigree too! I've written up a quiz answer key and posted it here. Look over my explanations and tell me if you still need help.

What's the plot of this story?

We have a new instructor now, and we have a new series of topics. Take a minute to think about where we've been, and where we are going.
First, we learned about what is inside a cell. You learned about the important biological molecules, and how they interact inside and outside the cell. You learned about how cells make and use energy. Then we started talking about mitosis, and meiosis, and now genes.... what's the story here?
Imagine the class is attempting to give you all the information you need to understand how an organism grows from a fused egg and sperm. You need to know:

1. How cells function in the mature organism - making proteins, maintaining electrochemical gradients, secreting signals into the blood, etc.
2. How cell functions are governed by genetic instructions in DNA.
3. How the genetic instructions for the organism get into the egg and sperm.
4. How mature organisms grow from a single fertilized egg.

So far we've covered step 1, some of 2, and all of 3. Much of the focus in the next weeks will be step 4. On Friday, we'll make sure you are equipped to learn all the information to follow! Print the worksheet here, and THIS week I want you to try to answer the questions before you come in. See you Friday!
