Segmentation genes determine the polarity of each segment

Homeotic selector genes specify the identity of each segment and direct the development of individual body segments. These are the master genes in the control networks of regulatory genes.

Transcription factors are polypeptides of around 60 amino acids which bind to genes further along the DNA and initiate transcription, so regulating the expression of other genes.

A morphogen is a substance that governs the pattern of tissue development by regulating the homeobox genes.

Wow do you know all this stuff, Ayla, or are you reading it from somewhere???

I'm reading from my textbook at the moment, but I will need to learn it all for teh exam :)

What class is it? Genetics? I love genetics !

Arthur: "Because his life's worthless!?!?!?!?"

 

Uther: "No. It's worth LESS than yours."

I love math, I finished Differential Equations last year.

 

fallacies... mathematical fallacies everywhere

this means that the gradient of the graph x=1 is 0, which is completely correct

 

Did you know that in linear algebra, you can redefine 0 in matrices to 1, in some cases.

Maths

What I really hate is English.

Doing the essays are really annoying.

I like reading though, the only part of English I actually like.

I wish we could read the Wheel of Time as one of our reading books.

I would love doing literary analysis on that.

I'm terrible at writing >.>
