A* Biology Off Spec Facts

As a studrnt aiming for an A* in biology, I have bern adviced to kearn some off spec facts to make the synoptic essay a cut above the rest.However, I am having difficulty finding some for many of the topic areas.

Here are a few of my own to get things started:

-Replication of DNA on lagging strand occurs in sections called Okazaki Fragments

-Upon formation of pre-mrba it is further modified with a methylated cap.Rhis allows it to diffuse out of nuclear pore.

Pre-mrna is further modified with a poly adenine tail bythe enzyme poly-A polymerase.This influences the length of time the RNA can exist outside the nuclear before being degraded by enzymes

-Totipotent cells are different pluripotent stem cells in that they are responsible for the formation of the throphoblast and the inner cell mass.Remaining celks are pluripotent and tbe inner cell mass will follow different germ lines.

-Maximum amount of mitosis for any one cell called the Hayflick Limit.

Again ANY additional facts would be greatly appreciated
Just be sure that they are of A-level standard.
