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
