Tonight's Reading

Please read chapter 13.  I will be giving you notes tomorrow as handouts, but always remember that notes are never a substitution for reading the text.  We will complete all of chapters 13 and 14 and most of chapter 15 for the final exam of the semester.  Put it on your calendar:  December 10th.

Test Tomorrow

Read through your powerpoints and written notes.  Look at major diagrams and charts in the text (especially if I have gone over them!)  Answer the questions at the end of the chapters again.  (It can't hurt.)  If you have any questions, please post.

Tonight's Reading/Studying

I thought I would make a list of sections in the text that you can skip when you're studying, so here they are:

Chapter 10:  None.  Sorry.:(
Chapter 11:  11.5, 11.7, 11.11, 11.13, 11.20
Chapter 12:  12.3, 12.4, 12.5, 12.14, 12.15, 12.17, 12.18, 12.19, 12.20, 12.21

That should alleviate some of the reading load.  I will check the blog for questions from around 8-10 tonight.

Tuesday's Study Questions

p. 251:  #1 (concept map)
p. 252:  #2-#7 (multiple choice)

There is no essay on the test on Friday. However...I want you to answer questions #12 and #13 under 'applying the concepts' on p. 252.  We had a short discussion about transgenic organisms today (think 'genetically modified food').  We will look at gene therapy tomorrow, so read page 241 tonight.  I want you to answer these two questions in paragraph form, making sure to answer each portion of the question.  (Number 12 has several sub-questions.)  I will take these Friday before the exam and count them as the essay portion of your test, so you can write over the next two days, ask me questions, and revise your work before you turn it in.

We will do a short activity on DNA fingerprinting and gel electrophoresis tomorrow and write a summary of the process.

In chapter 10 (which now seems LONG ago and far away), be sure you understand the DNA discovery experiments (Griffith, Avery, Hershey/Chase).  Also--DNA structure and replication.  There are several enzymes involved in replication.  A good way to keep them straight:  1)  cut notecards in half.  2)  write the name of the enzyme on one card, its function on the other.  3)  mix them up and see if you can match them. (This is actually a good way to learn all kinds of information.)

I will be around until standard time--10:30ish.

Tonight's Reading/Studying

Practice questions for chapter 11 to try tonight:

p. 228:  #1 (the concept map)
p. 229:  Multiple Choice--#2-8; Applying the Concepts--#10

Reading in chapter 12: 
1)  Look at figure 12.1 on p. 233--it is a good summary of gene cloning and possible uses.
2)  Figure 12.2 on p. 234 is a good illustration of how restriction enzymes produce 'sticky ends'.
3)  Read over pages 242-246.  We will be discussing these sections in class tomorrow.  You already have the powerpoint notes.  It would be good if you would read over those and get a general idea of how PCR and gel electrophoresis work.

*Don't forget:  The answers to all the questions at the end of the chapters are in the appendix of the textbook!

For next week

We will be discussing DNA technology, specifically--gene cloning, PCR, gel electrophoresis and DNA fingerprinting, and gene therapy.  We'll look at the pros and cons of this technology and how it is used in medicine, agriculture, forensics, etc...  Look ahead into chapter 12.  Read the headings, look at diagrams, pictures, etc... and read the chapter summary.  I hope to be done by Wednesday so we can review all block on Thursday; test on Friday.

Tonight's Reading/Work

On your iPOD, go to the Kahn Biology 1 app and listen to the lecture on viruses (it's #18).  It's only about 20 minutes long and it's quite good.  The reading in your text is pages 200-203 (viruses and viroids.)  Further reading for tomorrow includes pages 204-205 over bacterial genetics.  You already know what transformation and transduction are, so this should be easy reading.

Tonight's Reading

Read pages 191-198; have your powerpoint out as you read so you can jot down any notes or questions.  Feel free to read ahead and look over the main ideas about mutations and mutagens.

Study

Please read over both powerpoints tonight.  When you study, always start from the beginning of the current material and work your way up through the new stuff.  And...the chapters on the next test will be chapters 10-12, not 13-15 as I wrote on the board today.  But you've probably already figured that out.:)

Tonight's Reading

Read over the powerpoint notes from class today.  (Keep re-reading these notes EVERY night.  The more you read them, the easier they are to remember.)  Also, read pp.182-189 in your text.  We will be discussing DNA structure and replication in class tomorrow.  The material is not difficult; just a lot of it. 

For Tomorrow

Check your email tonight.  I sent five powerpoints to you for the next unit.  I tried to send them all in one email, but received 'fatal error' messages, so I sent them one at a time.  I have already printed them out for your notebook, so look over the first ppt tonight--DNA Discovery Experiments.  Also, it wouldn't hurt to look over chapter 10.

Questions?

I know the test is challenging.  But it should be.  There's a lot of information in these two chapters, so read over the sections that are giving you problems.  I will check the blog until around 10:00.
