This week has been the best week yet.  I've had a lot of fun but at the same time learned a lot.  On Monday, we learned about genetic drift, neutral theory, and coalescence.  I liked learning about genetic drift and how it was related to Hardy Weinbergs theorem.  The genetic drift theory was founded by S. Wright who realized that population leads to deviations and fixations.  Then, we learned about the neutral theory.  There are five things that evolve neutrally: non-conserved parts of protein molecules, the third positions of synonymous codons, introns, spacer between genes, and pseudogenes.  Coalescence is a complex but quite intriguing topic.  We learned about the molecular clock and selections as we learned about coalescence.  Coalescence will occur faster in a smaller population.  What I thought coalescence was after the lecture was that it explained how some species got lost, merged, or came together. There are two types that dont crossover ever, mtDNA and the Y chromosomes.  We learned about all of those topics in two days.  And on Tuesday afternoon, we got to actually see 3-D domains and proteins and see the mtEve phylogeny.  Katie and I tried to see how many different countries humans evolved from.  It was so much fun to play on the Blast.  I learned a lot and had a ton of fun.  On Wednesday, we learned about genetics and DNA.  James Watson and Francis Crick discovered DNA.  Crick came up with an adapter theory, where an adapter attaches itself to the RNA sequence.  We also talked about the genetic code and how 4 nucleotides with 3 positions have 64 codons.  Also, the genetic code has redundancy but not ambiguity.  I enjoyed learning about amino acids again.  I really like learning about molecules and how their charges, polarity, and hydrophobicity makes a difference of how they react and bond.
