We have just begun studying our fourth unit (Information). This week coming down after the Midterm exam, we mostly focused on Vodcast 4.1 and getting through the dense and extensive 4.2 Prezi. 4.1 introduced us to the background history of the research process of our modern understanding of DNA. 4.2 focused on the Central Dogma: DNA into RNA into proteins. 4.2 covered replication of DNA, transcription unto RNA, and translation into coding proteins. We also worked in class on a argument project to determine using hereditary data, whether "Jeff" was related to the family he claimed.
Overall I understood all the new concepts of this week and the new lesson. I owe this to the fact that the new Prezi was so extensive, being over 112 slides long, and the fact that I took almost equally extensive notes. At first the leading and lagging strands of DNA did not make sense to me and I did not see why lagging strands existed. However this confusion was fixed within a day when I "discoed" with classmates and returned to my notes at home. Even reading the data on Jeff's DNA markers for the argument project did not compute at first. But when I read through the evidence section of another classmates presentation, it was made crystal clear. It really helps to be able to discuss and share information with our peers.
As far as a connection to the context of the course, the information we're learning on DNA relates backwards to the very beginning of the course. DNA codes for the production of proteins and enzymes used in photosynthesis, the knowledge of bonds and structures from unit two explain the workings and directions of the DNA strands, and considering how colossal the amount of data there is to be processed and replicated it is far more comprehensible that mutations occur leading to natural selection of different genes.
