10/29 Biology update and homework due 11/5

Hi folks,

Today we went into great detail learning how we get proteins from RNA and how we get RNA from DNA.  In other words, protein synthesis.

Homework for this week is to:

Be sure to take all the definitions we started class with today and put them into your flash cards.  They will all be on upcoming quizzes in one form or another.  Memorize how the DNA & RNA bases pair as well.

Here's the list of terms from today's lecture. 

Protein Synthesis

Transcription

Translation

DNA

RNA

mRNA

tRNA

Codon

RNA Polymerase

Ribosome

rRNA

Adenine pairs with Thymine.  Guanine pairs with Cytosine.

In RNA Thymine is replace with Uracil.

Also:

Read pgs. 193-210

Do Chapter Review Questions on page 212 #'s 1 - 3, 9 - 14, 18 - 22  (Sorry for jumping around on this but I'm trying to skip some of the more "out in left field" questions.  I'm sure you won't mind.  :)  )

Do Standard Test Prep questions on page 213 #'s 1-8

Study the steps in transcription and translation that I put on the board today  They will be tested.  You have been warned! :)

Extra Credit Possibility for biology

Hi folks,

I mentioned this in class but I wanted to do a little write up to make sure all is clear.

For folks who might be looking for some extra credit, or, who would just like to work a little more with biology here's an opportunity.

First step, hit the Googles and find someone who's done something important in the world of biology.  It can be something to do with DNA, medicine, evolution, genetics, biomolecules or whatever else might strike your fancy.

Once you find that individual, email me with the person you're interested in.  At that point I'll give you the thumbs up or down as far as going ahead with the paper goes.

When you get the go ahead, write a small essay on the person.  At least one full page, typed, normal margins, single spaced.  Include things like; when did the person live; where did they live; what was their background; what did they discover; and why the discovery is important.  Be sure to include the sources you used to do the essay.  Try to find at least three different sources.

The more thorough the essay, the more points it will receive.  Maximum of 5 extra credit points.

This assignment is valid all year so as long as you get this to me before the final exam it can be counted as extra credit.

Have fun and good luck.

Best,

Jim Mueller

10/22 Biology update and homework due 10/29

Hi folks,

Today we wrapped up our work with the biological molecules by taking an in-depth look into lipids and proteins. We will be doing more with nucleic acids when we get to protein synthesis.

For homework this week:

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… :) ) Write down what you find and turn it in next week.

Also do the questions #1 - 8 on page 63.

Lastly, next week will be a fairly all inclusive quiz on the biological molecules. (This is why homework is fairly light this week.) I'd highly recommend studying the homework that I just handed back to you today (the questions from the email from 2 weeks ago). Study those old quizzes and make sure you master any questions you've gotten wrong. Also memorize/master the following if you haven't already.

Drawing the 4 biomolecules CHAN
Drawing the 4 functional groups CHAP
Knowing what enzymes do FRECC
The 8 characteristics of life MOSHGOD R
Examples of each of the CHAN
Which CHAP's are associated with what CHAN's
The names of all the monomers
The subcategories of the CHAN
The major functions of each CHAN
The prefixes and suffixes.
Why is water special

Bring cell phone to Bio

Hi folks,

If you can, bring a internet connectable device to class on Tuesday.  We are going to be doing a game show at the end of class.

Good news, no quiz!!!  But still keep memorizing those flash cards!!!!

10/15 Biology update and homework due 10/22

Hi folks,

Today we spent some more time reviewing those molecules we've been working on and we also took a closer look at carbohydrates.  Next week we will explore lipids, proteins and maybe nucleic acids if we have time.

Homework for this week is to read pages 50 - 61 in the text book and do questions 1 - 23 on page 62.

Part 2

10/8 Biology update and homework due 10/15

Hi folks, 

Today we discussed enzymes and five of their basic functions.  We also enjoyed the amazing thrill of learning to draw the monomers of the four biological molecules.  :)  Next week we will get into those quite a bit deeper.

There will be a quiz next week so be sure to focus on the material on this homework and keep memorizing those prefixes and suffixes.  

I've added today's words to the Quizlet we've been working with.  Here it is.

For homework next week:

 On either the flash cards I gave you or on your own:

Create flash cards based on the biological molecule chart I gave you in class last week.

Create a flash card for each of the four functional groups.

Create a flash card with the 5 things that enzymes do. (Remember FRECC)

Create flash cards with the four bio molecule monomers.

Create flash cards with the monomer and the associated functional groups.

Be sure to practice drawing those functional groups and those monomers.  YOU MUST DRAW THEM TO LEARN THEM!!!

Also, fill out the following set of questions. 

1. Which biological molecule stores energy? 

2. Which biological molecule is the main source of energy? 

3. Which biological molecule contain nitrogen? 

4. Name all the biological molecules that contain carboxyl groups. 

5. Name all the biological molecules that contain hydroxyl (if a hydroxyl is in a carboxyl, it's just a carboxyl). 

6. Which two biological molecules are associated with providing structure for animals and plants? 

7. Which biological molecule is vital for genetic information? 

8. Which biological molecule would be most associated with eggs? 

9. Which biological molecule would be most associated with vegetable oil? 

10. Which biological molecule is associate with cell membranes? 

11. Which biological molecule consists of a sugar and an phosphate group? 

12. Which type of biological molecule is a triglyceride? 

13. What kind of a biological molecule is insulin? 

14. What kind of a biological molecule is starch? 

15. What kind of a biological molecules are fatty acids associated with? 

16. What are the 3 elements all life is made from? 

17. What are the monomers of carbohydrates called? 

18. What are the monomers of proteins called? 

19. What are the two types of nucleic acids? 

20. What kind of a biological molecule is a sterol? 

21. If I'm talking about a polypeptide, what kind of biological molecule am I talking about?

Bring Cell Phone to Bio Class

Hi folks,

If you have a cell phone, please bring it to class today.  We are going to do a fun gameshow/review at the end of class today and we're going to use cell phones to do it.  If you don't have one that's fine.  We can work in teams as well.

See you all soon!

10/1 Biology update and homework due 10/8

Hi folks,

Today we discussed a bit of homeostasis and positive and negative feedback loops.  We also scratched the surface of the 4 major biological molecules. We will spend quite a bit more time on that next class.

There will be no quiz next week but I HIGHLY recommend taking that time to really nail down those prefixes and suffixes, the fuctional groups and memorize the other material we've covered up to now.  Also, put those flash cards I gave you to good use.  Make each square of the table we discussed today into its own flash card.  You'll memorize it pretty quickly if you spend time with it. 

For homework this week:

Read this website regarding homeostasis and answer the following questions that can be found in the reading.

1.  What are three things cells need to survive?

2.  What is homeostasis?

3.  What is negative feedback? 

4.  What is positive feedback?  

5.  Which is more common in biological systems, positive or negative feedback?

6. Give 3 examples of negative feedback.

7.  Give an example of positive feedback.

8. Give three examples of homeostasis in mammals.

9.  What is the job of the endocrine system?

10.  What are two basic ways disease and cellular malfunction can be caused?

11.  How does nutrition play a role in homeostasis?

12.  How does physical activity play a role in homeostasis?

13.  How does mental health play a role in homeostasis?

14.  Last but not least, how about environmental exposure?
