Document Summary
Cover 2a by myself, read chapter 2 (39-51), panel pg 66-69. Top are sperm cells, bottom is staining and there is a blood smear, tissue - small intestine: cells with in a tissue. Dark field microscopy, labelled proteins in a cell with colors, cytoskeleton: skeleton inside of a cell, thats what microscopy is for. Electron microscopy, two types: sem and tem, very advanced. Zoom into the trachea for an example, tem you take a slice and look at all the organelles. Sem just scans overall microbe, tem looks through it, you can see the nucleus and organelles. Central dogma: process for cells where you take dna template transcribe to rna, that message translates to amino acids and proteins. How an outside signal traduced inside to cell membrane. Highly conserved: term you will hear a lot, means module of process that works and see it used in many systems. Two types: pro and eu, pro has no nucleus, eu has nucleus.
