How are eukaryotic chromosomes organized
WebChromosomes Chromosomes condense and become visible by light microscopy as eukaryotic cells enter mitosis or meiosis (which we’ll learn about in the next reading). During interphase (G1 + S + G2), chromosomes are decondensed in the form of chromatin, which consists of DNA wound around proteins called histones. WebCalvin Cycle: Phase 1. Is the Carbon Fixation Phase. CO2 gets into the cell by simple diffusion because it is small and uncharged. The Objective is to trap 3 CO2 per cycle (hence C3 plant) This is done with the Rubisco enzyme which catalyzes the fixation of carbon ( CO2 attaches to the ribulose biphosphate carbohydrate through a covalent bond ...
