Document Summary
How cell as a whole compartmentalizes processes, where processes occur, regulation. Genome: instructions for how to make entire organism. Need materials (nucleotides, amino acids, lipids), need workers (enzymes to perform specific functions) Has a lot of same structure as cells in our body. Whole collection of yeast where 1 gene in genome is deleted, study how that gene affects cellular processes, learn about how our cells function. Understand how, what genes contribute to that process being disregulated. Have over 200 specialized cell types in our bodies, have different functions, different shapes. Nucleus: segregated from rest of cell by nuclear envelope. Lysosomes: stomach of cell, break down cellular components so basic building blocks like amino acids can be reused. Extracellular matrix: made up of long fibres of collagen and other components, more specific to animal cells. Plant cells have different kind of structural support. Plant cell wall gives plant cell mechanical support.
