Document Summary
Dates & times for purchasing lab manuals are on website- buy everything before first lab! Genomics, proteomics: viruses consist of protein and nucleic acids, living things have dna genomes and are cellular, every single living cell has ribosomes which are made out of rna protein. Metabolism: cells take up nutrients, transform them, and expel wastes, genetic, catalytic. Growth: nutrients from the environment are converted into new cell materials to form new cells. Evolution: cells evolve to display new properties. Differentiation: some cells can form new cell structures such as a spore. Communication: cells interact with each other by chemical messengers. Genetic exchange: cells can exchange genes by several mechanisms. Motility: some cells are capable of self-propulsion (for example, by flagella) Cell structure: plants and fungi have cell walls, fungi have chitin in their cell walls, some prokaryotes have cell walls, some don"t. Genes, genomes, nucleus, and nucleoid: genome, prokaryotic cells generally have a single, circular dna molecule called a chromosome.
