Prise de notes de l'UE BIO 301 : UGA DLST niveau L2 Cours sur le cytosquelette et sur les différents constituants de ce dernier

Cours sur la nature biochimique des microtubules, leurs rôles et dynamiques au sein de la cellule ainsi que les protéines régulatrices de ces derniers. Prise de notes de l’UE BIO 301 ; UGA DLST niveau L2

The actine is concentrated in the cell periphery, in this case the cells on the right are differentiated into neural cells. The functions of the cytoskeleton is: The three types of filaments: - Actine  helical polimers of a single protein called actine, they concentrate in the cell cortex and are important determining the cell shape and movement - Microtubules  are cylindrical polimers of alpha-beta tubuline dimers. They are larger and more rigid, involved in positioning cell org...

This is the process from which one cell divides in two daughter cells, genome information is duplicated and segregated. There are different stages in mitosis: - chromosome condensation in profase, nuclear envelope breakdown which brings you into pro-metaphase at which point the chromosomes are starting to align on the mitotic spindle that is alreading forming on the outside of the nucleous. - In metaphase there is an align state; once the cell has conformed that indeed al the chromosomes ar...
