Document Summary
24/09/2018: giemsa staining, most common chromosome stains, preferentially binds at-rich regions which tend to be gene poor, called g-positive, slinky -> as you stret(cid:272)h it out (cid:373)ore a(cid:374)d (cid:373)ore you (cid:272)a(cid:374) (cid:858)see(cid:859) (cid:373)ore detail, q21. 1 0, region. sub-region. Band: mitosis & meiosis, mitosis is a nuclear division, ending up with two daughter cells that are genetically like the parent, some cells completely stop dividing -> cardiac muscle-> terminally differentiated, mitosis, aabb --> aabb. -> ab: mitosis (m, short phase, chromosomes are highly condensed. Includes both nuclear division (mitosis) and cell division (cytokinesis) Long growth period (cid:373)ost of the (cid:272)ell(cid:859)s life: chromosomes are extended allowing for gene expression, not in a rod like shape -> more like a bowl of noodles. Includes: gap 1 (g1): normal state of non-dividing cells, cells may leave cell cycle and enter g0, an extended resting phase, synthesis (s): dna synthesis in preparation for mitosis, cannot go back to.
