Why use rat or mice? Why use monkeys instead of mice?Rat/Mice: Easy breeding & DNA altering
Monkeys: Complex processes -

What does a Golgi stain actually stain? What neural parts did this stain show?Stains: small % of neurons ENTIRELY dark
Shown:
- Soma (central region containing nucleus)
- Neurites (axons & soma)
- Because it stains entirely these are visible -
What is the neuron doctrine?Neurons are not connected (synapses)
-
What 3 things are roughly in the Soma of a neuron?- Cytosol: Water inside of the soma
- Different Organelles: Cell nucleus, Rough Endoplasmic Reticulum
- Ribosomes: Protein synthesis structure in cytoplasm
Cytoplasm: everything in som except nucleus -
What is the function of mRNA?Carrying genetic (DNA) message to the cytoplasm to start the protein synthesis (expression of DNA)
-
What is transcription when talking about DNA?Acids in the nuclei represents the genetic information
The process of DNA --> mRNA messenger -
What is an Exon portion of a gene?Part of a gene that gets expressed in the protein
-
What is translation when talking about DNA in Neurons?The process of mRNA forming the Amino Acids
-
What is a genome?ALL DNAL: Entire length of DNA info in our chromosomes
