Some of the graphics that I used in class

Hi folks,

Here are some of the graphics I used in class on Friday.  They may be helpful to print out and study.

Recording for 11/21 class - Nucleic acids and DNA replication

http://youtu.be/Yea0FOc7_9w

11/21 biology class and homework due 12/5

Hi folks,

This week we discussed nucleic acids a bit more and got started on DNA replication.

Remember, no class this week due to Thanksgiving. May all your turkeys have excellent DNA.

Homework due 12/5 is to:
Read pgs. 193-210
Do Chapter Review Questions on page 212 #'s 1-22
Do Standard Test Prep questions on page 213 #'s 1-8

Study the steps in transcription and translation…they will be tested…you have been warned!

Happy Thanksgiving,
Jim Mueller

Recording for 11/14 Biology Class - Enzymes and Proteins

11/14 Biology update and homework due 11/21

Hi folks,

Today we covered enzymes and proteins.  Homework for this week is to read the following website.  Don't  worry about clicking on the follow up links unless you're interested on your own.  http://www.chemguide.co.uk/organicprops/aminoacids/proteinstruct.html

Also, we saw a small video in class showing the different structural levels of protein.  Here's that video. http://www.youtube.com/watch?v=lijQ3a8yUYQ

Answer the following questions based on the lecture and the website information.

1.  What is the basic pattern of atoms that you see when amino acids combine?  For example c-c-o-n-c-n etc.

2.  What is the method by which amino acids combine?

3.  What types of bonds hold amino acid residues in their shapes?

4.  What is meant by denaturation and what can cause that?

5.  Why is it important that proteins hold specific shapes?

6.  What is a fibrous protein?

7.  What is a globular protein?

8.  What two functional groups are on an amino acid?

9. How many amino acids are there?

10. Describe the differences between the 4 different structural levels of proteins.

11.  What are the 5 different subcategories of proteins?  Give an example of each one and what it does.

12.  What are 4 things that enzymes do?

13. What is meant by "Lock and Key" when it comes to enzymes?

14. What is meant by the active site when it comes to enzymes?

15.  What is meant by the substrate?

11/7 Biology update and homework due 11/14

Hi folks,

Today we basically spent the entire class on a lab where we used different indicators and attempted to find which foods contain which biological molecules. There will be no recording for this week since we spent the majority of class on the lab.

Homework for this week is to complete the enclosed .pdf.
Remember to study those flash cards!!!!

Oct 31 Biology update and homework due 11/8

Hi folks,

Last class, we spent a bunch more time on those unbelievably exciting biological molecules!  I know folks can't wait to do more with those, so your homework this week is to create flash cards of all 4 of the biological molecules and all the functional groups we went over in class.  Use index cards and put the name of a group or molecule on one side and then draw the molecule on the other.  I'd highly recommend using them to test yourself as well, since the next several quizzes will certainly have a bunch of those on there.  You will have to draw the molecules or groups for the quiz.  You'll also need to know what functional groups are associated with what biological molecule.

Also, using your new knowledge, see if you can find 3 things that would be a good representative of something containing lipids, something containing nucleic acids, something containing proteins and something containing carbohydrates.  3 things for each molecule so 12 things all together.  These need to be things you can see/touch around you.  (Hint…look in your fridge… :)  )
