BIOLOGY STUDY SESSION April 30, 2007 cell theory photosynthesis resd dna structure mitosis/meiosis repl, txn, tln gene expression genetic engineering cell theory: fluid mosaic model fluid goes all around cell, cell is constantly moving. Danielli model was Unit Membrane Hypothesis. Proteins are in membrane, made up of phospholipid bilayer. ER is continuous with nucleus ribosomes can be on Endoplasmic reticulum lysosome – cleans up cell, if it ruptures, apoptosis occurs. mitochondria – powerhouse of cell (in both plants and animals) chloroplasts – photosynth happens there, contains stroma and thylakoid plant cell has cell wall with vacuoles replication: making of new DNA, happens in nucleus. DNA DNA = replication. RNA = transcription protein = translation in cytoplasm/ribosomes. at this point language changes: ATGATCTTT turns to UACUAGAAA by transcription. becomes codons through translation in pairs of threes. codons combine to become polypeptides photosynthesis: stroma + thylakoid in chloroplasts. two reactions. synthesis/dark/light independent reaction takes place in stroma. NADH, ATP, and carbon used in dark
