Document Summary
C e r e b r o s p i n a l. Central dogma of molecular biology: dna (transcribed) rna (translation) Affects how well drugs work on us and addiction. Epigenetics: information transferred down to generations but not through your genes. If dna is loosely bound to histones it"s easy to transcribe to rna, if tightly bound it"s hard to transcribe. Transgenic animal: has something in its gene you wouldn"t find in nature, it genome has been changed. Gene has been altered or a gene from another animal is injected. Knockout animals: targeting a gene and knocking it out - cause animals to not be viable. Conditional knockout animals: inserting something into diet and it knocks out a gene (ex. The inside of a neuron is negative, usually -60v to -80v. Originally performed in invertebrates because they have very large neurons. Result of two ions: sodium and potassium. Ions move into or out of the cell but not freely.
