what we did in class 12/12/09

This week in class we learned about how DNA works. We learned that DNA gives of a code and that is how the cell knows how to function. We also learned the process of DNA. First DNA gives the cell a code. The mRNA then copies the code and gives it to the ribosomes. The ribosomes then crack the code. Then the solved code is given to the tRNA which gather all of the supplies needed to carry out the code. They then give the code to the ribosomes to build and now we have a protein.

We also learned how the proteins are actually made. The DNA strand unwinds releasing the code. Then the U base pair matches with the A base pair. The code is copied as many times as needed. then the RNA strands are read as a codon or a triplet. Each code represents an Amino Acid. this happens with every triplet and with every triplet make, one goes away leaving the Amino Acid and bonding with the other Amino Acid on the other triplet. This happens until the strand is complete and now you have a chain of amino acids. Using ATP it becomes a protein.
