Q2 – Week 2 – 11/22 – 11/23

                                                                                                                              Jump to:  Tuesday,   Wednesday,  Thursday,  Friday                                                                                                                                   ___________________________________________________________

11/22 – Monday –  B Day 

Main focus –                                                                                                                                                          
a)  To identify three molecular parts of DNA.
a)  To identify how deoxyribose is numbered 
1. DNA activity begins – everyone will have individual google slide to complete along with me.
Please make sure you open that email and link before we begin.
DNA is another example of a polymer because it is made up of repeating nucleic acids.
Remember that proteins are also polymers because they are made up repeating amino acids.
Each individual nucleic acid bonds to other nucleic acids by removing water to make a phosphodiester bond that links the phosphate group to the sugar. An H is removed from the phosphate and and OH is removed from the sugar and thus a water is removed. This is another example of dehydration synthesis!
Now we have 2 nucleic acids, RNA and DNA.  They only differ by they type of sugar in the nucleic acid AND they use the nitrogenous base uracil instead of thymine in the case of RNA.
Given the differences between ribose found in RNA and deoxyribose in DNA what nucleic acid was being synthesized above?
                                                                                                                                                                                                                                                                Here is the Codon Chart that represents the DNA code for all amino acid.

Video for today’s activity if I went too fast! –  nucleic acid monomers become polymers (polynucleotides)



11/22 – Monday’s Homework: –

1.  Please watch my video below that will complete the slide that we were working on today.  Please work with with me to finish the slide that we were working in class with. I will give you instructions on how to complete your homework from the sheets that I gave out today in the video as well.                                                                                                     
YOU MAY NOT NEED THE VIDEO TO COMPLETE THIS SLIDE that should have a total of 6 nucleotides when completed.                                             
Please take a look at my screenshot that I did after you guys left today. All I did was number the carbon in the deoxyribose (sugar). We always count starting from the Carbon next to the Oxygen.
Also notice that I bonded the third nucleotide by creating a phosphodiester bond that links 3 Carbon (on the sugar) to the phosphate of another nucleotide. I used white boxes to take out the 2 hydrogens and 1 oxygen (that becomes water in another example of dehydration synthesis).
Please add this to your presentation before you begin viewing the video.

11/23 – Tuesday –  A Day – 

Main focus –                                                                                                                                                          
a) To correctly make a 2 dimensional 6 nucleotide anti- parallel strand with appropriate base pairing and phosphodiester bonds.


 *Ordered  Sordaria Firmcola from Wards to arrive Next wed.

 1. Please correctly cutout, tape a double stranded DNA molecule that correctly codes for the first 2 amino acids in your protein that you folded last week. It must be anti-parallel!  You will need a total of 12 nucleotides that will make a 6 nucleotide code from 5′ to 3′.
A) Make sure that you create phosphodiester bonds by cutting out 2 H’s and 1 O atom (removing  
      water) to link nucleotides AT THE 3rd Carbon.  
B) Make sure you mark with dots the correct H-Bonding that occurs between nucleotides.
C) Make sure you put a A,T,C,or G inside the nitrogenous base of each nucleotide.
D) Make sure you label each of the four ends with 5′ or 3′ ending!
E) Make sure that your DNA correctly codes for your amino acid sequence from the 5′ to the 3′          direction.
F) Put your name on your DNA!
IF you need more nucleotides!

It will be collected and graded.



11/23 – Tuesday’s Homework: –

                                                                                                                                                                                                                                    1.  Please enjoy your family and please dispel and myths about tryptophan!     


                Based on the above chart you can see that turkey does not have the greatest amount of proteins with tryptophan.
         AND NO tryptophan does not make you sleepy!!!  If it did vegetarians would always be asleep because they love tofu which is                   made of soybeans!
                                           Also if that myth was true turkey sandwiches would have warning labels like, 
                                                        “Do not operate heavy machinery while digesting turkey!”
                                         How many tryptophan related accidents would we have on Thanksgiving?
