breezy friday!

Homework:
Finish up 39-40 due: Monday
Read 13.3
Chicago Tribune 11/23
TEST 11/23

Today in class we went to the science lab to do a online class work.
The pages to the work were in the packet pages 39 to 40 and was homework if you didnt finish in class. The link to the website is found in the side in resources. Test and Tribune are due in tue and make sure to read 13.3 by Mon!

Its Thursday!

Today in class we did a lab that was kind of like a fallow up on our last lab when we built the DNA. We built the DNA again then unzipped then made the other side RNA. That was to show transcription. Then we unzipped the mRNA from the DNA strand and moved it to the ribosome in the cytoplasm where translation occurs. Then we had to construct the three tRNA molecules and place three basses on it that are complementary to the first three nucleotides of the mRNA strand. The three nucleotides on the tRNA are called anti~codons. After that step we attached the amino acid to the tRNA molecule by its R~group. Then we disconnected the a.a chain from the tRNAs and the tRNAs from the mRNA and can be reused. This activity was called "Protein Synthesis Activity".

HOMEWORK:

~Finish UP 15-20 - due tomorrow

~UP27-28 - due tomorrow

~Test next tuesday the 23rd

~trib article - due tuesday the 23rd.

Extra Credit

EXTRA CREDIT ON BLOG
Today in Biology we had a late arrival which meant that we had less time to learn about DNA and RNA.

Some Notes that we took in class were

Transcription (RNA Sythesis)

One strand of DNA serves as a template for synthesis of mRNA
Occurs in the nucleus
RNA polymerase joins RNA nucleotides

Then we watched a video and from the video we learned that

The first codon is always AUG
Amino acids form together to form a peptide bond
tRNA looks for another amino Acid
If you link a bunch of amino acids together then you form a protien
Ribosomes make protien

More Notes

Translation (mRNA to Protien)

mRNA attaches to a ribosome
Each tRNA carries one amino acid
Anticodon on t RNA matches with a codon on mRNA
Amino Acids bond together to forn a polypeptide chain
Long polypeptide chains make a protien

Other Notes

Anticodon-series of three bases found on tRNA
Codon-series of three bases found on mRNA

Every codon codes for 1 0f 20 amino acids
