I am sure that everyone did a great job on the benchmark today! We did a lot of review and it seemed pretty easy. Remember that I do not score these and I can't enter a grade until the BOE scans them. So, I should have them in the gradebook as a 5th quarter grade when we come back from break.
No homework tonight or over break.

Have a fantastic vacation and we will begin Natural Selection when we come back.

Study for your benchmark and if you did not finish the mRNA/tRNA synthesis worksheet, finish it tonight.

Today we went over the answers to yesterday's benchmark review packet. Below you will find today's class notes. The benchmark is Thursday. Make sure you review tonight.

Today I was on a field trip with my Environmental Science class. You had the Benchmark III packet to complete in class today with Ms. Ferguson.
 This is a great review for the benchmark on Thursday.  If you used your class time wisely today, then you may have finished it in class. If not, it is due tomorrow. We will go over it in class.

Today we reviewed for the unit test on Genetic Engineering.  You have everything you need to study, which includes the notes from last week.The packet from class today has a repeat of this information in the reading.  This is actually a good reading and directly relates to what you need to know for the HSA. The key and warmup from today's classwork is posted below.

Next Thursday March 29th is Benchmark III. This covers Asexual/Sexual reproduction, Genetics, DNA/Protein synthesis and genetic engineering.

Today we continued with the movie Food Inc. to see real life applications of genetically modified foods.
There was no homework last night, but you do have an assignment due Thursday.
Read 15.2 and outline it. Also, complete pg. 354 questions 1-3. Remember you must restate the question.

Wednesday we are in the computer lab doing an online activity on Gel Electrophoresis.
Thursday- Test review
Friday- Unit Test on Genetic Engineering (Chapter 15). Also, use you notes from class to help you study
Know the vocabulary from the packets (transgenic, clone, gene splicing, recombinent DNA, gene therapy etc.) These are the same words we reviewed in class warm-ups too.

The notes from today are posted below.
Please finish the AR on gene technologies this weekend. It will only take 5 minutes or so.

Today you took the 3rd quarter re-take. If you were absent, you can make it up tomorrow during lunch. I was surprised at how many of you did not want to do a retake.  It can't hurt your grade, it can only help you! On the other hand, I have kids trying to replace a "low" grade of an 85 taking it. Good for you!  That shows you really care about your grades!  Every point matters toward your GPA.

After the test you started tonight's homework
Read chapter 15, section 1 pg. 345-348
Complete Quick lab pg. 347 1-2 and the Review questions 1-3 on pg 348.
I will collect this tomorrow and the DNA Fingerprinting activity I gave you yesterday.

Today we went over the DNA quiz and the asexual and sexual reproduction test in class.  You were also able to see you genetics test card and a copy of the test if you wanted to in order to help review. Very few of you actually did this and it would have helped you review what you did not understand on the original unit test....
I also was available during lunch if you wanted extra help.

You were given an activity to introduce gel electrophoresis. This will be due on Friday. Most of you finished it in class today. This procedure is used to link suspects to crimes and in court to prove paternity cases.

Tomorrow 3/15- 3rd quarter retake
Monday 3/19- warm up quiz
Wednesday 3/21- end of 3rd quarter. Summer will soon be upon us!

Mutation Notes

Here are the mutation notes from today.

Complete the IR if you did not finish it during class today.  This week we will spend time mutations and get into genetic engineering.

Remember the 3rd quarter retake is Thursday and the Warm-up quiz is Monday. This has been on the board since last week.

We will end the month with Benchmark III and then we will begin ecology. Something you can finally relate to!

The averages were really high on the Protein Synthesis and DNA test. Great job!  The overall average was an 85. No homework this weekend.

Today we took our unit test on DNA and Protein synthesis. Next, we start mutations and genetic engineering.
Homework: Finish the 14.1 outline that you started in class after the test and try to get outside and enjoy this beautiful day!

Yesterday I was out of school and you completed the test review in class. Today we went over that review.
Tonight, finish the review on protein synthesis. I have attached the key below so you can check your work.
Tomorrow is our unit test. Good Luck!

Complete the worksheet on Transcription and Translation tonight.
We will continue to review over the next 3 days.
Our unit test is Thursday March 9th.

Today we took notes on protein synthesis and completed a worksheet called Breaking the Code.  We reviewed DNA synthesis and took a close look at protein synthesis. I have attached the powerpoint notes.

Homework: Finish the worksheet on Breaking the code. This covers DNA synthesis and Protein synthesis.
If you were absent today, you missed a lot of information. You will need to get with me next week to go over all of this.  It can be confusing and it is a lot to remember. Remember, if you ever come to school late, come and see me to get what you missed in class that day.

Great job on the DNA quiz. The averages for all periods was between an 83-88 percent!

Today you should have finished your Bio2Go on protein synthesis in class. Tomorrow we will take notes on protein synthesis. This is a fairly detailed process to remember.

DNA has the direction on how to make a protein. Remember that DNA can't fit out through a nuclear pore, so it stays int he nucleus. mRNA copies DNA and brings the directions on how to make a protein out to the ribosomes in the cytoplasm.  It is here, that tRNA reads the codons on mRNA. The codons are a series of 3 nitrogen bases.  tRNA has the anticodons to match up to the codons. Each codon codes for a different amino acid. It is tRNA that brings in the amino acids to the ribosomes.  Proteins are simply chains of amino acids and there are 20 amino acids.

Below is a diagram of a protein being made.  You can see the long mRNA chain on the ribosomes. The tRNA molecule is bringing in the amino acids. See the chain being formed?

Nice job on the quiz! The class averages for all periods were between and 83-88!

Today you should have completed the Bio2Go on protein synthesis. TOmorrow we will take notes on protein synthesis. It is more detailed than RNA synthesis.  I have several review sheets that we will complete to prepare for our unit test.  The unit test date is still not set in stone. Perhaps the end of next week, or the beginning of the following week.

The following diagram shows mRna attached to a ribosome and the tRNA molecule reading the codons ( series of 3 nitrogen bases) as it brings in the correct amino acid. An anticodon on tRNA macthes up with a codon on mRNA.
Remember, a protein is a chain of amino acids and theere are 20 amino acids.  The length and the ordering of amino acids is what makes proteins different from each other.
