ed: Let’s keep it going for bread! Woo!

I’ve had both of these photos on my blog before, but I need to clarify, whose bread photo is whose. The above photo is by Van Robinson, but does anyone know who made this photo, please??

DNA Chromosome Wrapping - what makes it possible for a six foot long molecule to fit into the nucleus of every cell in the human body! This entire process of forming into the familiar chromosomal shape only happens right before a cell is about to divide. 

You see those ‘hooks’ on the proteins the DNA is wrapping around? They are a part of that ball-protein called the Histone (H3). They help link other neighboring segments together (like what is happening in the 3rd and 4th gifs) because they stick out so far from the histone core allowing them to be covalently modified and effect gene expression.

These histones are also packed with positively charged amino acids because the DNA backbone is negatively charged from the phosphate groups.

You can even see your own DNA pretty easily. Check this video out and let Brian Cox teach you how to see your DNA.
