Document Summary
Biology class notes 3 (dev lecture, developmental genetic and cancer & genetically modi ed foods) Circuit board >take code and turn them into functional phenotypes (evolutionary genetics) Not dna, not phenotype but the middle ground. How we go from code to interphase. Start with single cell and it becomes many and a variety of types. Totipotent: can become any kind of cell (embryo and placenta) Pluripotent: can become any kind of body cell. Multi-potent: can become a few di erent kinds of cells. The more they grow, the more they get identity. As development goes forward, can"t go back and change it/ become something else. Coding sequence= make our gene (controls what protein will be made) Doesn"t always have to be on, could be o , make a little protein, make a lot of. Di erential gene expression= gives us the ability to organize into functional organisms. Cells express a unique set of genes.
