Day 28, Skipping Out of Order, Chapter 26, pp 510 --

 Mitosis, meiosis, and genetics can get very confusing;  when you add protein synthesis with RNA it gets very complicated.  Basically you have a lot of the different ways DNA can be used (with mitosis, replicating to supply a new cell;  with meiosis, dividing and combining;  with protein synthesis, reading with RNA).


I feel like it would be best to separate the topics.  So I'm going to skip from chapter 12, mitosis, out of microbiology and to the different forms of life.  After each section I'll go back and fill in something with genetics and reproduction, and protein synthesis.


Obviously if anyone is using this blog you can just find and use the links for the chapters in order if you'd like.


Today's work is easy for me -- start off with this interactive timeline of life on Earth, clicking on each link and watching each video.  Don't forget to click the arrow on top to progress on the timeline, at one point it expands because the time intervals change drastically.

Day 21, pp. 138--154

Campbell-Reece is organized from small to big, which is fine, but we'll never get to prairie dog colonies if we don't punch it up a bit so we're going to do more of a survey and less detail for a bit.


Heavy on the amoebas this time!


Fluid mosaic, phospholipid bilayer, proteins


more details and transport


cell signaling


osmosis


cell transport



brief ted on cell membranes


last, bozeman to top it off


sodium potassium pump
