This week we have been focusing on DNA and its replication process. To help us understand this complicated process we have done several POGILS about the structure of DNA and the replication process. For homework we have been taking notes on a massive Prezi that breaks down the replication process even more. Our WSQs have been broken down into three parts in accordance with the prezi, replication, transcription, and translation. These notes have been a bit overwhelming, but thanks to my colorful pens, drawing it out makes it easier to understand.
Before jumping into the replication process we did a Vodcast about the basics of DNA, and it’s history. From Friedrich Miescher's discovery of nucleotides to Hershey and Chase’s discovery of DNA being the molecule of heredity (4.1), this gave us great background information into DNA’s long discovery process. We also worked on a Biointeractive in which we explored different theories of how DNA is replicated, after drawing this out, and using the information we found that DNA is replicated in a semiconservative kind of way. This was a great segway into the POGILS we did later on in the week.
So far we have done a POGILs on DNA structure and replication, and how it’s transcribed. I'm still a little fuzzy on some stuff, but doing these POGILS are really helping me understand the information from the prezi.
It was really fun at the end of the week to take the knowledge we’ve learned so far to generate an argument about whether or not Jeff (a long lost child), is actually the real Jeff and is related to Mr, and Mrs. H. By looking at an STR test, we were able to confirm that “Jeff,” was not the child of Mr, and Mrs. H. This argumentation exercise was really fun.
