(37 cards)
cell
basic unit of biology
cell theory
- all organisms consist of one or more cells
- the cell is the basic structural unit
- cells only arise from preexisting cells
cell biology
cytology + biochemistry + genetics
cytology
study of cells
microscopy
visualization of cells
light micrscope
earliest tool of cytology, ID of organelles
antibody
protein molecule produced in the immune system that binds to a target molecule (antigen)
limit of resolution
how far apart adjacent objects must be to appear separate
resolving power
ability to see fine details of structure
electron microscope
uses a beam of electrons with EM field instead of visible light
biochemical
compound made by living organisms
enzymes
biological catalysts
centrifugation
separating and isolating structures based on size, shape, and density
ultracentrifuge
resolving small organelles and macromolecules
chromatography
a mixture of molecules in solution separated into individual components
electrophoresis
electrical field separates macromolecules based on mobility in gel
mass spectrometry
determines protein size and composition
genes
hereditary factors
chromosomes
threadlike bodies in dividing cells
bioinformatics
merges computer science and biology
CRISPR
clustered regularly interspaced short palindromic repeats
organic chemistry
study of carbon-containing compounds
biological chemistry
chemistry of living systems
bond energy
amount of energy required to break 1 mole of bonds
