Document Summary
Ontogenetic provides control of specific neurons at specific times in behaving animals. Action potential are propagated by movement of + ions across membranes (depolarization) Na+ moves into the inside through pores. Action potentials can be controlled using channelrhodopsin from chlamy. Channelrhodopsin allow positive ions (creates an action potential) to enter the cell when there are flashes of blue light. Blue light causes opsin to change shape, thus opening up the pore. Placing channelrhodopsin into neurons allows us to control action potentials with light. Genes can be grabbed from the nuclei (ndna) by using restriction enzymes. Genes can be created by reverse transcription of mrna into double-stranded. Genes can be synthesized directly from dna printers , gene machines . Only works for small sections of dna. 4-cutter sequence will cut the genome into smaller pieces. Process by which the gene inserted inside a plasmid is inserted into a cell. Cells can be induced to take up plasmids directly from the environment.
