Document Summary
Rate of diffusion is directionally proportional to interface surface area. Not leaky to salts, or large polar molecules (>h20 , like sugars ) Dna is of bacterial origin and encodes some of the genes for electron transport. Binary fission: cells grow, duplicate all major cellular constituents (dna, ribosomes etc. ), distribute this content, and then divide into 2 nearly identical daughter cells. Used primarily by single celled bacteria and archaea. Genetic material isn"t enclosed in a membrane-bound nucleus. Occupies a location, the nucleoid, within the cell. Proteins aid in compacting the dna into a smaller, organized structure. Bacterial chromosome is typically attached to the plasma membrane at about the midpoint of the cell. Mitosis - used often by eukaryotes in processes of cell division not associated with sexual reproduction. G1- cell is accumulating the building blocks of all cellular components and accumulating enough energy reserves to complete the task of replicating each chromosome in the nucleus.
