What is a cell= the short version

 Cell Biology 101

In my upcoming Podcast (now published: Spotify and Google) I'll go through some background for what an mRNA vaccine is:

 I want to do is take you a little deeper as I mentioned if you listen to the trailer my goal here is talk about the iceberg behind what what we see in the traditional media. 

What I want to share here is a simple whiteboard session that goes through the basics:

I do want to start off with is when we look at a mammalian cell or A to use the fancy term a eukaryotic cell it's broken down into into zones and regions the two major ones that most of us have heard about is the is the cytoplasm and the nucleus so the nucleus is the central part of the cell it's kind of the the central processor to steal a computer term of the cell and the cytoplasm is where all the action happens and this is all bordered by two lipid structures and so when I say lipid structures way that I I would ask you to visualize it is if you took an orange and you cut it in half if you looked at it from the side in the central you'd see that white pithy area that to the nucleus and that's not a bad representation of the size of it and then you would see all the wet shape structures that would be the cytoplasm then on the outer edge you'd have the white and the orange and that's actually a pretty good representation of the the outer layer that that defined the cell and and so the so the way to think of it is all those areas that are white which orange is called the pith all those are actually would be in a in a cell would be lipids so those would be the equivalent of butter that's the most reasonable fat or lipid that I that I can that I can make the analogy to so we have really three important zones that we have to we have to talk about to really understand what a cell is; 

1. The membranes  that protect and define the cell from the environment and create specific zones for discrete functions.
2. The cytoplasm which is where most functions of cells gets done
3. Nucleus you can think of this as the central processer of the cell.

The thing is our cells are just like a building that we built with proteins. They are going to wear down overtime so you need a mechanism that allows you to recognize that protein has broken down and you need to replace it and so again this is some of that signaling So what that what that signal does is when the cell recognizes the protein that is broken down or it's not doing its job properly send a signal to the nucleus that says hey I need a new copy of the scaffold gene and there's a variety of them I'm not going to get into the gene names here. 

This process of transcription is managed via 2 important functions; the nuclear pore which allows mRNA out and signals in AND by the cell surface pores and receptors which let the cell know what is going on the in the wider world.

Just a little quick post christmas whiteboard!

more to come.
