S is for Sister Chromatids

Sister chromatids are two identical chromosomes attached to each other at the centromere. Since they are identical, they carry exactly the same genes. So what's the point of having two identical chromosomes attached to each other? This is the body's way of making more cells. When it undergoes mitosis the DNA needs to replicate itself so the new daughter cell will have the same amount of genetic material.


Sorry for such a short post today, it's currently student appreciation weekend and I'm focusing all of my energy on feeling appreciated. Out of everything that USP does incorrectly, they always nail SAW. Tons of free food, live music, and bouncy castles. What more could a college student ask for? A free shirt? Got one of those too.

Oh, how awesome, you're blogging about biology! Complete with illustrations! This makes me very happy; I'm only sorry it's taken me this long to catch up with your blog.

You have a terrific time being appreciated and flopping around in the bouncy castles. :)
