BIOL 1000 Lecture Notes - Lecture 1: Nuclear Membrane, Nuclear Pore, Cell Membrane
Document Summary
Lecture #8 sept 26: protects the dna controlling what goes in and out of a cell see what goes in and out control. In: double membrane (2 phospholipids bilayers, have nuclear pores very complex structure have components in them to help, proteins, transcription factors/enzymes, nutrients. Eukaryotic dna and non-histones proteins: involved in gene transcription. Eukaryotic dna packing: histones then you can transcribe them packing: chromosomes are made of chromatin, all histones have the same function, histones associated with bacteria are different but have the same role. Insulin synthesis and secretion: regulation of blood glucose, made of two chains and joined together by disulphide bonds, when it is translated it does look like it takes lots of modification for it to. Fuses with the golgi bodies b/c similar membranes. Proinsulin is not at the level of membrane. Exocytosis: vesicle is made of golgi membrane and fusion occurs and releases it.
