Document Summary
*read objectives at beginning of slides to test yourself f. Head: choline, phosphate, glycerol, polar, hydrophilic tails fatty acid, nonpolar, hydrophobic. Living cells are dynamic systems with energy flowing, used to produce dynamic order, to build new molecules. Micro filament (actin subunit) keratin, an intermediate (slightly larger) filament (polypeptide strands, twisted) All cells in your body have a nucleus except red blood cells. Four nucleic acids: adenine, thymine, guanine, cytosine (a,t,g,c) g c, a t (hence double helix) Dna is capable of self-replication this happens for cell division and protein synthesis. Synthesis of new proteins: transcription from dna to mrna (m for messenger, translation from mrna to protein. Proteins are synthesised in the rough er (the er with ribosomes on its surface) Proteins: large organic compounds made of amino acids arranged in a linear chain and joined together. Synthetised proteins play different roles in the cells.
