Genome DNA of a living organism constitutes (controls actions in cell controlled by protein)
Genes specific regions of genome that encode instructions for building RNA and protein
Proteins Carry out most of the activities of life, including the synthesis of all other biological molecu;es
Central Dogma DNA- RNA (Amino Acid) -Protein
Metabolism how body takes in outside food sources breakdowns to get energy
Photosynthesis Produces own food
Cellular Respiration breaks down biological molecules with oxygen, releasing chemical energy
Homeostasis Maintenance of a steady internal condition by responses that compensate for changes in the external environment
